Eren's POV:

When (f/n) told me to never change, it made me feel... wanted. As if I.. I mattered to someone as myself, and not a titan shifter. Not the world's one chance to connect in some way with the titans. Little did she know, I felt the same way about her. This world had changed her. Ever since the first day I met her. That angered me... To know that someome as amazing as (f/n) had to live in a world like this. It was honestly cruel. But I hugged her back. It was a small way of letting her know that... I love her, and that she was one of the last things in this world that kept me sane.

Then it stopped... It all stopped. As soon as I put my hands on her, her body began to spark brightly, following with a mass of matter morphing in my arms. There was no time to question or express exactly what the hell was happening, it just...happened. and whatever it was, I must've triggered it.

With that, I was blown away from (f/n), and the castle began to crumble above where we had previously stood. 
'What the hell is going on!?' I questioned myself, pushing the castle's rubble off of me, and waited for the dust from the damage to clear.

And I couldn't quite explain what I saw next. Was it beautiful? Amazing? Horrifying? Terrible? I had no fucking idea. I didn't know whether to be surprised, or... Frightened.

A 13 meter titan stood before me with (h/l) (h/c) hair and (e/c) eyes that pierced my soul.. but I knew exactly who's eyes those were. I couldn't forget them.

"(F--f/n?) My lips quivered as her name tumbled out of my mouth.

The titan shrieked in response, still staring right at me.

The titan's body had half of its body (the top) covered in (s/c) skin, and the other half (bottom) covered with lean muscle.

The titan began to grin at me, bearing a smile that made a chill travel down my spine.

"EREN!!" I heard someone call from a distance. I turned my head in the direction of the voice, and saw Captain Levi and his squad sprinting in my direction.
"Eren! No one gave you permission to trans-" Petra's words were cut off when she caught a glimpse of the titan standing before me.
Changing their goal of gaining control of me, they instead shifted their focus to their 3-D gear, and began grappling into the titan's neck.
"It's.. It's an abnormal... It's another female titan!" Gunter screamed.
"NO!!! DON'T KILL HER, ITS (F/N)!!" My voice exploded from the depths of my throat.
And with that, the entire special operations squad froze in their very positions on the titan.
(F/n) still hadn't moved, and was still grinning sloppily, as if she was drunk.
Levi ungrappled from (F/n)'s wrist, and came soaring in my direction.
"Stand down, for now..."  I heard him sternly order to his team, who silently obliged.
Levi landed right in front of me, slightly glaring. His expression made me tremble, even more violently than (F/n)'s grin.
"Eren, what the fuck is that?" Levi asked me calmly.
Shit.
"It's.. it's (f-f/n), sir..." My voice stuttered.
Levi shook his head as soon as the sound of (F/n)'s name reached his ears. " Tch. Two. Two of you I have to deal with now. Tell me, Eren. When and how exactly did this happen?" Levi asked in a sarcastic tone.
"I-I um hugged her, and all of a sudden, she.. she just transformed.."
Levi shook his head in disbelief.
"Pain, Eren. Its caused by pain, and a goal. That makes no damn sense."
"Captain.. I don't really know what happened, but.. maybe she's different. Maybe she's not like me and Annie."  I contemplated with him.
It was unsettling seeing that (f/n) ended up in the same position as me. It was as if everyone around me was becoming my nightmare, and there wasn't a single thing I could do about it. Levi looked up at the frozen titan, and motioned to his team.
"We need something to make her transform back into a human... Any ideas anyone?"
Levi questioned everyone.
Everyone shook their heads including me.
Then Gunter smirked. "Eren knows how to wake her up. He's the one who caused her to transform after all,"
"Hh-huh!?" I perked up, and felt a blush heating up my cheeks.
"Eren, you're not fooling anyone. Just yell her name or something. Tell her what you really feel." Petra smiled.
So apparently my crush on (f/n) wasn't a secret to anyone. But Levi and the others are right. Maybe if I say something to her, she might come out of the trance she's in.
"Okay... I'll try, I guess." I quietly whispered.
I walked in vicinity of the motionless titan, and took a brief pause.
Please wake up, (f/n).
"(F/N)!!! WAKE UP!!! PLEASE!!!" I screamed, in a determined effort to get her to snap out of it.
"That's not going to work, Jäeger. You know what to do." Levi spoke up, crossing his arms.
I sighed. This is not the way I wanted to tell (f/n) that I love her. I didn't want it to be forced. I wanted things to come on naturally and slowly, just like the way I fell in love with her.
"(F/N)!!.. I..I... I LOVE YOU!!!" my voice echoed from the bottom of my throat, and vibrated against trees for miles.
Her (e/c) hues peaked up, her eyes widening, and the sadistic smile dissapearing from her face.
Smoke began rising from her position, signaling that she had begun to transform back into a human.
Within minutes, half of the titan body had evaporated into thin air, and her body became visible from the nape of her titan's neck.
"(F/n)!!!" I called her name, as I ran to retrieve her.
I pried her out of the titan corpse, and she seemed to be unconscious. I ran my fingers down her cheek. I...I did this to her.. I turned her into a monster.
Like.. like me..
"E-Eren..." I heard (f/n)'s voice tremble from her lips.
I focused my attention to her lips.
Her reply was broken, and barely audible, but I understood it with crystal clear precision. Despite what I'd done to her, what I'd put her through, she still felt the same way for me. "I..I-I lo-ve you too.."
