Requested by GalaxyRose2871: Tom is a devil and Y/N is an angel. They're dating and see each other on the border between heaven and hell. Y/N wants to cross the border with Tom, but she can't because her family doesn't want to be associated with the devils. Y/N's father disagrees with the relationship and demands that she stops it. She refuses and decides to cross the border to be with Tom, and turns into a devil.

I sat on the wall, my eyes looking over the contrasting land as my wings rested against the brick on either side of my legs. They needed a rest as much as the rest of me did, and so I always got to mine and Tom's meeting point a few minutes early to give them a chance to recover.

"Hey, my love." I looked up, and my heart immediately fluttered.

"Tommy." I smiled, making him return it as he walked towards me along the wall, and I stood up. Immediately, my wings flapped into action and lifted me up, making my boyfriend laugh and shake his head as the feathery limbs propelled me towards him. Within seconds, I was in his hold, his arms tightly wrapping around my waist in a tight hug as I held his face. I leant down and smashed our lips together, him returning the kiss immediately as our eyes fluttered shut. I felt Tom's fangs gently and teasingly pull at my bottom lip, the action always making my heart flutter even more as we kissed. I broke it after a moment and opened my eyes, Tom's chocolate and red orbs looking back at me as he held me up.

"I missed you so much, darling." He whispered and shook his head as his gaze flicked between my eyes and my lips.

"I missed you too." I returned. He smiled and pecked my lips again, making me giggle as he put me down and we sat back down on the wall with Tom's arm wrapped around my waist. Tom and I had been dating for a year now, all of our dates characterised by hours of cuddling, kissing and...other things...on this very wall. This of course wasn't what we wanted, but it was the way that it had to be if we were to continue seeing each other. And that was due to the simple fact that I was an angel, and Tom was a devil. We had met a year ago completely by chance, when I had come to this wall that overlooked the border between heaven and hell. Tom had had the same idea, and we had bumped into each other. I had been terrified at first, and Tom had loved that, the boy appearing arrogant and in love with my fear when we had first met. Angels and devils weren't meant to mix, and so whilst angels were taught to be terrified of devils, devils were taught to relish this fear, and to make it ten times worse. That had been what had happened, with Tom's hand around my throat within seconds and his fangs having threatened to pierce the skin. But then something had changed. The second that we had looked into each other's eyes, we both knew that this wasn't like a normal angel-devil encounter. For starters, the fact that Tom had one chocolate eye and one red eye instead of the matching red eyes that were normal for devils, had made him more pure to me, less evil than other devils. And something in my eyes had made Tom see a slight mischief, slight evil that wasn't enough to make me a devil, but was enough to make me not as pure as an angel should be. We had fallen for each other there and then, and had been seeing each other ever since. But of course, it wasn't as simple as this. Our families had found out about our affair, and to say that my family was outraged was an understatement. Tom's family was admittedly proud of him, for they saw our relationship as him managing to corrupt the purest creature on earth, whereas my family, and angels in general, never wanted anything to do with devils. They had resented Tom for making me fall for him, which of course only made me want to be with him more. Right now, I was still biding my time, but ultimately, I wanted to cross over the border into hell, and be with Tom once and for all.

"Does your family know that you're here, sweetheart?" Tom asked as he leant down and softly pressed his lips to my shoulders that were exposed due to the straps of my dress.

"Not through me, but they will do. The gatekeeper will have told them or something. Someone will know. But it doesn't matter. Because the next chance that I get, I'm crossing with you." I nodded as I looked at him. His eyes widened slightly, Tom's head raising to look at me as they did.

"What? You're ready to cross over, darling?" He asked hopefully.

"I've been ready for a long time, Tommy. I need to go back once more, but then I'm gone. I'm yours." I promised. Immediately the biggest smile that I'd ever seen spread onto my boyfriend's face, making me laugh as he leant in and kissed me passionately again. I returned it and held his face, my heart only falling for Tom more once seeing how excited he was that I would soon be returning to his world, and staying there.

"I can't wait, sweetheart. I can't wait to spend the rest of eternity together." He nodded as he broke the kiss, and touched our foreheads together.

"Neither can I, Tommy. Neither can I." I whispered, making his smile widen as he leant in and kissed me again.

I crept into the palace, my pumps barely making a sound against the marble floors as I tried to get in without being heard. Even my wings were limp in an attempt to be quieter, the feathers silently brushing against the floor as I crept through. But of course, I was destined to be caught.

"Where have you been?" I stopped in my tracks, my eyes fluttering shut and my wings perking up as my father's voice called out, and echoed through the building. I gulped harshly and turned around to look at him, his face as hard as stone as he stared emotionlessly at me.

"Why are you asking that if you know that I was with him?" I shrugged, my mind knowing that there was no point in denying anything. My father definitely knew that I'd been with Tom, and so lying would only make the situation worse. He scoffed and shook his head.

"Do you really not see how you've changed since being with him, Y/N? You would never have dared talk to me like that a year ago. He has poisoned you-."

"He has set me free." I spat back. My father's face hardened again, tears pricking my eyes as I realised this for what it was. This was the end of my life in heaven.

"If he has set you free, go to him. But know that once you do that, you do not come back. If you leave this home again with the intention of seeing him, you are no longer welcome here. And you never will be again." He shook his head. I gulped and nodded as a tear left my eye, the magnitude of what I was doing finally hitting me. But all I felt was freedom. For millennia, I had felt trapped as an angel, I had felt trapped by the rules and regulations that bound us to our duties, and cursed us for interacting with anything that wasn't our kind. I had only started to feel free once I had met Tom. And so, it was time to finish that transition, and go to him. Go to him, and to hell.

I stood on the wall, my wings limp by my side as I stared at the border of heaven and hell. The one that I would cross once Tom got here. As if on cue, I felt his presence behind me, my heart exploding into butterflies in my chest as his fingers raised and gently pushed my hair off of my shoulder before replacing the strands with his lips.

"Are you ready to do this, my love?" He whispered gently against my skin. I nodded and bit my lip as I turned around to look at him, his gorgeous eyes flicking over my face and his small and soft smile on his lips as he curled his arms around my waist.

"I'm ready." I whispered. He returned my nod and maintained his smile, making me take a deep breath as he leant down and tightly hugged me. I returned it, tears starting to leave my eyes as he took a step back, and walked us off of the wall. But instead of falling like a mortal would, we stood on air as Tom slowly but surely started to walk us into the realm of hell.

"This may hurt, sweetheart, but I promise that it'll be okay. I'm right here, and I'm not letting go." Tom promised into my neck, making me gulp and nod as I held onto him for dear life. As soon as we sunk into the wall of hell, the slight sting started. I hissed and squeezed my eyes shut as I felt my wings start to wither, Tom's arms tightening around me in an attempt to reassure me as I held onto his neck with everything in me.

"Tommy." I choked and shook my head as it lulled forward to rest on his shoulder, the pain getting worse by the second as my hands gripped tightly onto his shoulders.

"I know, darling, it'll be over soon, I have you." Tom promised. I squeezed my eyes shut again as I felt my body continue to change, the sting getting unbearable...before stopping. Just as quickly as it had started, all of the pain stopped. My eyebrows furrowed, my eyes fluttering open to look around in confusion. I looked up at Tom, making the love of my life give me a smile as he looked over my face.

"You did it, my love. You're now a devil. And you're even more beautiful than you were before." He smiled and shook his head. I returned it and bit my lip, pure excitement filling me at the fact that I had finally done it. I had finally joined Tom, and crossed over into hell.

"Come on, Tommy. It's time to start our new life together." I smiled.

"Fuck yeah it is." He smirked, making me laugh as he took my hand, and started to pull me further into the depths of hell.
