Requested by BangtanNaekkeo: A mix between Marvel and real life, where Tom is Spider-Man and Y/N is a HYDRA agent. They are dating in secret and don't know the other's secret identity, and so Y/N has no issue when she gets sent to bring Spider-Man down. They both get captured by HYDRA, and Tom gets revealed to Y/N when his mask gets pulled off. Tom gets imprisoned by HYDRA and tortured, including electro-shock therapy to his brain that makes him forget who Y/N is. The Avengers save him, and Y/N has to remind him who she is, which makes him fall in love with her all over again.

I sat at my kitchen table, my fingers rapidly typing against my keyboard as I did the work for my fake job. It was such bullshit that I still had to do work for a job that was purely cover for my real work, but I had argued about that enough, and had been beaten enough in return for it. Suddenly, my phone started to buzz against the table. I sighed and bit my lip as the unknown number told me exactly who was calling. Meaning that I had to pick up. I rolled my eyes to myself before picking up my phone and pressing the green button before holding my phone to my ear.

"Agent Blackflower." I picked it up.

"You have an awaiting mission." The female robotic voice sounded.

"Continue." I nodded.

"Awaiting mission: capture and kill...Spider-Man." My ears perked up at the sound of that name. I didn't even have to think twice about this decision. Not that I ever had a choice.

"Mission accepted." I spoke before lowering the phone and hanging up. I smirked and bit my lip, butterflies of anticipation starting to flutter in my stomach at the idea of finally getting to kill my enemy. And I would enjoy every second of it. I looked over my shoulder as my doorbell rang to signal my boyfriend arriving at my apartment. I stood from my chair and practically skipped to the door, excitement filling me at my upcoming mission as I opened it. Tom looked up at me as the door opened, my stunning boyfriend's lips curling into a smile as he stood with his hands in his leather jacket pockets.

"Love, hey. You okay?" He chuckled as he moved into my apartment and shut the door behind us before curling his arms around my waist.

"I'm amazing." I sighed in bliss, making him smirk and shake his head as he leant down and kissed me. Tom and I had been dating for the last six months, and it had been incredible. The boy and I had first met ten years ago in high-school, but hadn't dated until recently due to neither of us having admitted our feelings for each other. The only thing was that we hadn't told anyone yet, not even his own parents and family. We knew that once we told anyone, the public would get a hold of the information in no time, and then our relationship wouldn't be just ours anymore. And so, we had kept our relationship under wraps. But being with Tom wasn't the only secret that I kept, my other secret was even kept from Tom himself. And that...was that I was a HYDRA agent. I hadn't chosen to work for the extremely evil and corrupt organisation, I had the pretty typical story of having been taken by them as a child, and raised to be a killer. I had just about managed to convince them to let me go to school so that I could fit in with other people and cover up what I actually did, that action having led to me meeting Tom. I loved him to bits, the boy meant the world to me, and that was exactly why I couldn't tell him about my real job. About my real life. No. He couldn't know that I killed people for a living. He could never know. And so...he never would.

"I'm sorry, I'm sorry, please, stop, please." I choked, tears pricking my eyes underneath my mask and my wrists becoming raw from the rope that held them together as the HYDRA agents pulled me into the compound. After Spider-Man.

"Shut the fuck up, you're not helping yourself here." Pierce spat, making me gulp as we were led into one of the cells.

"Get off of me, get the fuck off." Spider-Man snapped as the guards forced him down onto the chair before starting to tie his wrists and legs to the arms and legs of the chair. I gulped harshly and continued to fight against the guards as they made me watch, though my hands being tied behind my back didn't help. To say that my mission hadn't gone according to plan was an understatement. It had started off well enough, I had ambushed Spider-Man at the end of his patrol. That had been pretty much the only thing that had gone right about the mission, though. I had thrown a good few punches and had somewhat injured the superhero before we had both been surrounded by HYDRA cars, and had both been captured. Which had led me here, being held and restrained by guards whilst they also tied Spider-Man down to the chair.

"You failed the mission, Blackflower. I must say that I'm very disappointed." Pierce sighed and shook his head, both Spider-Man and I still struggling as he was now completely tied down to the chair.

"You didn't even give me a chance to complete it." I spat.

"Because he almost escaped, Y/N! We do not let our targets ESCAPE!" He yelled back. I choked and shook my head, my heart racing in terrified anticipation of what they were going to do as Pierce turned to face Spider-Man. He started to raise his hand, making the superhero's white eyes widen.

"Wait, what are you doing, stop!" He exclaimed as Pierce grabbed his mask and pulled it off of his head. And that...was when my world stopped. My eyes widened, my breath hitching in my throat as I came face-to-face with Tom's beautiful and yet battered skin, and unruly hazel curls. The boy panted heavily, his jaw clenched, and his lip split as he stared daggers at Pierce. Luckily, I still had my mask on, meaning that Tom couldn't see that it was me, but right now, it felt like my heart was being pulled out of my chest. A painful numbness started to creep over every inch of my body as the realisation that my boyfriend was my enemy hit me like a fucking truck. I had fought and tried to kill my boyfriend countless times without even realising, not to mention the fact that he hadn't told me about his secret. Though, I couldn't blame him that much for that given that I had done the same. But right now, the fact that I was faced with my beaten-up and run-down boyfriend who was probably about to be tortured at the hands of my employers was killing me inside.

"What do you want us to do with him, boss?" One of the HYDRA guards asked, Tom's face still hard as stone as he desperately pulled on his restraints. I on the other hand had lost all energy and willpower to fight, my glassy eyes glued to the love of my life as my mouth hung open in weary shock.

"Shock him. I don't want him to have any knowledge of the Avengers by the time that we're done." He nodded. My eyes widened underneath my mask, as did Tom's.

"No, fuck you, no, get away from me." He spat, the boy squirming and fidgeting as the HYDRA guards hauled me out of the room. I let them pull me into the control room next to it, my body as limp as it could be whilst still walking myself as they stood me by the one-way mirror that looked into Tom's cell. A tear ran down my face, my heart fucking breaking at seeing my boyfriend struggling so futily as more guards filled the room with equipment to start the shock therapy with. Tom never stopped yelling out and fighting as they placed the two stickers on his temples, the white circles connected to wires as a guard took the two clamps. I choked and shook my head, every inch of me knowing that what I was about to see would easily haunt me for the rest of my life as the guard raised the clamps to the stickers on Tom's head. As soon as the clamps touched him, he yelled out loudly, his eyes squeezing shut and his hands clenching into tight fists as the current started to run through him.

"STOP! PLEASE, STOP, PLEASE!" I screamed, my head snapping back and realising what was happening as all of the fight returned to my body. The HYDRA guards grabbed me again as I desperately fought and pulled at them, though they didn't let me go as Tom's pained screams ran through me like chills. It stopped after a moment, his body going limp and his chest rising and falling in heavy breaths as his head lulled forward. I choked and looked to the side at Pierce as he walked into the room.

"Pierce, please stop this, I'm begging you, it's my fault that I failed, not his." I sobbed and shook my head.

"The mission was to kill Spider-Man, Blackflower. The mission hasn't changed. It just won't be carried out by you anymore." He stated simply. My eyes widened, my heart once again plummeting to my feet as I knew exactly what he meant by those words.

"Please spare him, I'm begging you, please." I choked.

"Take her to her room. I don't even recognise her right now." He grumbled and shook his head.

"Please, Pierce, please, stop, please!" I screamed, my pleas and fights falling on deaf ears as the HYDRA guards dragged me out of the room and back towards mine, the desperate and horrifying screams of Tom ringing out through the compound as they took me back to the space that I was forced to call home.

Tom's P.O.V

Never-ending currents of electricity coursed through Tom's whole body, the boy yelling and screaming at the top of his lungs as his wrists desperately pulled at his restraints. But of course, his fighting was to no avail. After what felt like an eternity, the currents and the excruciating pain that came with them finally stopped again, giving the beaten and close-to-death boy a sweet moment of relief as he panted heavily, and his head lulled forwards. His eyes drooped as he fought to stay awake, though it was a fight that he was losing. Tom had lost track of how long he'd been held captive by HYDRA, but he knew that he'd been there for at least a few days now. And every day had been filled with hours of torture in the form of inhumane levels of electricity being sent relentlessly through the boy. It was too early to say for sure how much it had fucked him up, but he already knew that some of his mind was becoming increasingly fuzzy. If it weren't for his body still being clad in his Spider-Man suit, the boy would have forgotten what colours it consisted of, and he'd completely forgotten the name of one of his twin brothers. And then there was the faint outline of...a girl. Tom gulped, his heart still racing as he desperately tried to remember more details about the silhouette, but he simply couldn't. All he knew was that whoever this girl was, she was important to him. But he couldn't remember a name, a face, even what the relationship was. And that broke Tom's heart. He raised his head wearily, his heart sinking as the HYDRA guard raised the clamps in front of him once again.

"You ready for another round, pretty boy?" He smirked.

"Please, for the love of god, no more. Please." Tom choked and shook his head.

"I think that he's had enough too." Before Tom knew what was happening, two metallic hands grabbed the clamps from behind the guard and raised them to his head. The boy's eyes widened as the guard got electrocuted before falling to the ground. He gulped and looked up, a wave of relief immediately washing over him as Tony and Steve rushed into the room.

"Oh, thank god. Took you guys long enough." He sighed in relief as he slumped relaxedly into the chair for the first time since he'd been captured.

"Well, we're here now, kid. You okay? What have they done to you?" Tony asked as the pair started to untie him.

"Electro-shock therapy. A lot of it, too." He gulped. Steve and Tony returned it as they looked at each other.

"That doesn't sound good. We'll get you back and get Bruce to run a full scan and test on your brain. You're going to be okay." Steve reassured, making Tom nod as the two men helped him up and put his arms over their shoulders to help him out. Despite Tony and the Cap's kind words, Tom already knew that he'd lost some cherished and important memories to the shock therapy, ones that he didn't know whether or not he'd get back. And right now, that was terrifying him.

Y/N's P.O.V

I walked along the street, my heart in my throat almost suffocating me as I walked to Tom's parents' house. I had heard through my contacts that Tom had been rescued by the Avengers two days ago, but that he was so injured that he was currently recovering at his family home in Kingston. And, well...I had to see if he'd still remember me. After all, I'd seen plenty of HYDRA's prisoners go through exactly what he had, and I knew that plenty didn't come out with any memories that had been present before. I was just terrified that the same had happened to my beloved Tom. I walked up the path, my heart pounding so harshly that it almost bounced out of my chest as I raised my shaking fist and knocked it gently against the door. I heard quiet shuffling from inside as I desperately tried to swallow my nerves. After a moment, it opened to reveal the woman who I knew to be Tom's mum, Nikki. I gulped harshly as her eyebrows furrowed.

"Can I help you?" She smiled kindly, making me gulp again as I opened my mouth to answer.

"H-hi, um...I-I'm-."

"Oh, are you that friend of Harry's?" She chuckled. I hesitantly shook my head in response.

"N-no, actually, I'm...I'm a...friend...of Tom's." I lied, my eyes wavering as it broke my heart to say those words. After all, I had to remember that Tom had never told his family about us, and so I couldn't admit to it if he hadn't told them himself, especially if he'd actually forgotten who I was.

"Oh, okay, of course! He's in his room, just go right up." She smiled as she stepped to the side and let me into the house.

"Thank you." I returned the smile, though my body was still filled with nerves as I headed up the stairs. I got to Tom's door and once again placed a gentle knock against it.

"Come in." His soft and muffled voice responded. I took a deep breath and closed my eyes, my mind only just starting to prepare itself for the possibility that he wouldn't remember me. After all, if that turned out to be the case, well...it would kill me. I opened my eyes again and opened the door, making Tom look at me as I walked in. His eyes widened, his mouth falling open slightly as he saw me. I turned and shut the door before looking back at him.

"Hey." I gave him a small smile, the boy gulping as his eyes were seemingly locked on me.

"H-hey." He returned with a slight chuckle.

"C-can...can I sit?" I asked hesitantly.

"Please, yes! Go ahead." He smiled. I returned it and bit my lip, anxiety still coursing through me as he sat up in his bed, and I sat down next to his legs. I could already tell from Tom's reaction that he had no fucking clue who I was, and so right now I was just trying to hold myself together for long enough to assess how much I had to remind him of. No matter how painful that was.

"Do you remember me, Tommy? Do you know who I am?" I asked as I looked at him. The boy's face dropped slightly, his mouth closing slightly as his gorgeous chocolate orbs filled with sadness.

"I-I'm sorry...no, I don't." He admitted with a shake of his head. I nodded and stuck my tongue into my cheek as I looked down, my entire being becoming fucking numb as tears started to leave my eyes. It hadn't mattered how mentally prepared I had thought that I'd been, it hadn't mattered that I'd known before I'd asked that Tom didn't recognise me, it was still tearing me apart inside. And I doubted that that feeling would ever stop.

"I-I'm sorry, I didn't mean to upset you." He gulped. I shook my head and looked back up at him as I forced a small smile onto my lips.

"It's not your fault, Tommy. It's not your fault that you don't remember me." I reassured him gently. He gulped again and looked at me as his eyes flicked over my face.

"Well...how about you remind me who you were to me? Maybe that'll help me to remember?" He suggested. I gulped and bit my lip as I looked at him. This was where the pain started all over again. Because I knew that I couldn't remind Tom of who I was to him. If I told him who I was, he'd feel obligated to feel the same way again, to love me again, and that wouldn't be fair on either of us. No. I'd decided from the second that I'd seen him first be electrocuted that if he did lose memory of me, I couldn't tell him who I was to him. I had to let him figure it out himself. No matter how much that hurt.

"I'm sorry, Tom, I can't. It's not fair to you if I remind you. You have to figure it out yourself, but I'm sure that you will." I forced another smile as I leant forward and gently put my hand over his that was resting on his sheets. He gulped and looked at me, so much pain and sorrow in his unknowing chocolate eyes as he looked at me. My heart fluttered as he gently put his other hand over mine in return, but I knew that that was more than likely just to make me feel better, not because he knew who I was. "Yeah. I'm sure that I will too." He nodded, making me return it and bite my lip as tears continued to stream down my face, and my heart continued to break.

Tom's P.O.V

Tom lay on his back in his bed, his eyes flicking over the cracks in the ceiling that he'd seen hundreds of times in the days that he'd been on bed rest. It had been two days since the Avengers had rescued him from HYDRA, and things had been tough to say the least. He hadn't realised how much the shock therapy had fucked up his brain until he'd gotten home, and had discovered that whilst he knew who they were, he couldn't remember the names of two of his younger brothers, or his dog. He dreaded to think about what else he may have forgotten, but of course, he had no way to remember. All he could do was gradually discover what he could remember, at the same time as also gradually discovering what he couldn't. The boy raised his head to look at his closed bedroom door as he heard a gentle knock against it.

"Come in." He spoke. The door opened, making Tom look at the girl as she walked in. Immediately, it felt like his heart was lighter. His eyes widened, his mouth falling open slightly as he saw the most stunning girl that he'd ever seen in his life. Everything about her was just perfect, everything from her gorgeous, textured hair, to her beautifully coloured eyes, to the most sexy and stunning body that Tom had ever seen. He was in love already.

"Woah." He whispered to himself as the girl turned and shut the door before looking back at him.

"Hey." She gave him a small but beautiful smile, the boy gulping as he simply admired her.

"H-hey." He returned with a slight chuckle.

"C-can...can I sit?" She asked hesitantly.

"Please, yes! Go ahead." He smiled, his heart racing at the idea that clearly, this girl knew Tom in some capacity. Right now, he was just begging that she wasn't just a friend to him. Though, of course, he couldn't remember. The girl returned the smile and bit her lip, the action causing butterflies to erupt in Tom's stomach as he sat up in his bed, and she sat down next to his legs. It was killing him that he couldn't remember who this girl was to him, he couldn't even put a name to her stunning face. And yet somehow...she felt oddly familiar. Almost as if she was the silhouette that had been hanging around Tom's brain since he'd been tortured. But of course, there was only one way to find out if that was her after all.

"Do you remember me, Tommy? Do you know who I am?" She asked as she looked at him. The boy's face dropped slightly, his mouth closing slightly as his mind filled with sadness over the fact that he truly did not recognise her. Or he did, but didn't know how.

"I-I'm sorry...no, I don't." He admitted with a shake of his head. The girl nodded and stuck her tongue into her cheek as she looked down, making Tom's heart break even more as her changed position didn't stop him from seeing the tears freely leaving her gorgeous eyes. It didn't matter if Tom couldn't place her in his life, it was hurting him even more that she was upset, especially given that he was the reason for that.

"I-I'm sorry, I didn't mean to upset you." He gulped. She shook her head and looked back up at him as she clearly forced a small smile onto her lips.

"It's not your fault, Tommy. It's not your fault that you don't remember me." She reassured him gently. He gulped again and looked at her as his eyes flicked over her gorgeous face that he could already tell that he'd never get sick of just admiring.

"Well...how about you remind me who you were to me? Maybe that'll help me to remember?" He suggested. She gulped and bit her lip as she looked at him. Tom could tell that she wanted to, that she wanted to just blurt out how they knew each other. And yet...something was stopping her.

"I'm sorry, Tom, I can't. It's not fair to you if I remind you. You have to figure it out yourself, but I'm sure that you will." She forced another smile as she leant forward and gently put her hand over his that was resting on his sheets. He gulped and looked at her, so much pain and sorrow in her broken eyes as she looked at him. Her eyes wavered as he gently put his other hand over hers in return, it just broke his heart that it was clearly just a gesture of empathy, and nothing more. It couldn't be anything more at this point, no matter how much Tom wanted it to be.

"Yeah. I'm sure that I will too." He nodded, making her return it and bite her lip as tears continued to stream down her face, and Tom's heart continued to break.

~Two and a half years later~

Y/N's P.O.V

"Seriously, Tommy, I will kill you if I fall because of you." I threatened, though my giggle deceived me as Tom walked me along to an unknown location with his hands over my eyes.

"You try to kill me on a daily basis, wouldn't be anything new." He teased. I gasped and shook my head, making him laugh and kiss my cheek as I smirked at the teasing. It had been two years since Tom's memory had been erased, and so much had changed, at the same time as somehow staying relatively normal. Despite my heart being broken over the fact that Tom had failed to recognise me, I had wanted to give us another chance, and so had stuck around regardless of him not recognising me. Thank fuck I had done. Within only weeks, it was clear that Tom's deep feelings for me were starting to reignite his memories of us, my heart slowly being put back together as I could see him falling in love with me all over again. We had had our 'first' kiss one night underneath the stars, when Tom had finally plucked up the courage to ask me out again. Of course I knew the truth of our relationship, but again, I had wanted him to find his own way back to that. Part of the process of recovery for us was revealing our secret identities to each other, with the Avengers helping me to leave HYDRA and join them so that Tom and I could fight crime together as good guys. And so here we were tonight, celebrating our two-year-anniversary, as well as my one-and-a-half year anniversary of becoming an Avenger. And I was so glad that we were back to normal.

"Okay, I'm stopping you, don't fall." Tom warned, making me chuckle and shake my head as he stopped me in my tracks.

"Three...two...one...open." He moved his hands, my eyes fluttered open, and then immediately widened at what I saw. My lips parted to let a gasp out, making Tom smile and curl his arms around my waist from behind as my eyes scanned over the beautifully decorated garden that sat on the roof of the Avengers' Compound.

"Oh, Tommy..." I breathed out, my heart so full of love at the effort that he'd clearly put into this as my eyes flicked over the beautiful fairy lights that decorated the wooden canopy. Underneath the shelter of the structure sat a white-clothed table for two, red rose petals decorating the otherwise white canvas as a bottle of champagne in an ice bucket sat waiting to be drunk. It was perfect.

"Do you like it, sweetheart?" He hummed softly into my ear. I choked and shook my head, tears pricking my eyes as I turned around in his arms to look at him.

"Are you kidding, Tommy? I love it. It's perfect." I choked with a teary smile.

"Good. Because I wanted everything to be perfect for when I did this." He nodded before letting me go and digging something out of his trouser pocket. My eyes widened, my shaking hands raising to cover my mouth as he got down on one knee in front of me. Tears started to leave my eyes rapidly, my heart racing with love and adoration for the love of my life as he opened the ring box to reveal the most gorgeous diamond engagement ring that I'd ever seen.

"Tommy." I sobbed, making him smile and bite his lip as tears also ran down his face.

"Darling, I think that it's fair to say that the last two years for us have been crazy. We went from being happy, being comfortable, to me not even knowing how you were significant in my life. But fuck am I glad that I figured it out, because I would be so lost without you. You truly brought me back from the brink, and for that, I will always love you. Without even trying, you reminded me of who you are, of why you're so special, of why I love you so much. You've helped me so much in my journey to getting my memory back, and that was only made more special and concrete when you gave up HYDRA to join me and the Avengers instead. I can never express how much I love you for all that you've done for me, but this feels like the best way to try. I never want to live another second of my life without knowing you again. So, Y/N Y/M/N Y/L/N, will you marry me?" He gulped. I choked and shook my head, my mind taking in his incredibly beautiful words, and sending them straight to my heart.

"Yes, Tommy, oh my god, of course I will!" I sobbed. He choked, his eyes wavering in relief as he shot up to his feet. His arms flew around my waist in a hug, me returning it tightly as we cried into each other's shoulders. I pulled away but only enough to be able to see him as I leant in and smashed our lips together. Tom returned the kiss, both of us smiling and laughing into it as we enjoyed the intimate moment.

"I love you so much, sweetheart. I love you so fucking much." He choked and shook his head as he gently slid the perfect ring onto my finger.

"I love you so much too, Tommy." I whispered in return before kissing him again. I had lost Tom two years ago, and that had been the worst period of my life. So, never again would I take for granted these moments, the moments of kissing him, hugging him, waking up to his arm over my waist first thing in the morning. I would never take him for granted again, because I had lost him, and had been lucky enough to get him back. But one thing was for sure. I would never lose him again.
