'Y/N exposes little amounts of information about what happens, but chooses to cuddle with Eren instead.'

Your p.o.v:

"I saved you." I told Eren, holding him close. Eren looked at me with half-lidded eyes. "Saved me from what?" He asked, puzzled. "Don't worry about it right now, Eren. Rest." I said to him. He nodded drowsily and I rocked him gently, hugging him closely and warmly. He eventually fell asleep.

Eren's p.o.v:

I had a horrible dream... A dream where I turned into a Titan. Shaggy black hair, pointed ears, glowing turquoise eyes, exposed teeth... God, I couldn't control myself. I was murdering all my teammates. Marco, Jean, Mikasa, Armin, Sasha- even sweet little Krista! Why can't I control myself?! All of a sudden, I let out a huge shriek, and a flood of Titans ran my way. They tore into my flesh, eating me skin and bone. I howled in pain...

*end of dream*

I woke up gasping, surprisingly being cradled by [y/n]. A thin film of sweat covered my face and body, as well as the fact that I felt as if I'd been crying. [y/n] held me close, stroking my cheeks and hair. "Shh... rest..." she repeated in my ear, and eventually, I fell into a dreamless darkness we call sleep.

Your p.o.v:

I embraced Eren tightly, welcoming his warmth. I saw he was sweating and had been crying. I kissed his forehead and stroked his hair.

{Time skip}

Eren woke up once more, this time 'normally'. His eyes fluttered open. "Morning..." he said groggily, facing me with a wide but sloppy grin. 'Hopefully he didn't remember I kissed his forehead...' I thought to myself.

Eren's p.o.v:

I knew that [y/n] had kissed me, but I wouldn't dare tell her. I just snuggled into her like a pillow. She was warm. "Hey [y/n]?" I asked, "mhm?" She replied. "While I was unconscious... I heard you mutter something about someone named 'Yoko'..." I started, trailing off. [y/n] gulped. "Yoko was my best friend. She was with me during everything. Hardships, happiness, fear, love, hatred. She turned out to be a Shifter, and was put down. Not killed, but put into an induced coma. She'll only be freed if I free her. Eren... i- I don't want to talk about her. It breaks my heart seeing her... she's like sleeping beauty. Yoko really loved you, Eren. Truly with all her heart." I give a sad smile as I finish speaking. Eren looked at [y/n] with a speechless expression. "O-Oh..." was all he could say. I held him close, crying into his shoulder. I wanted Yoko back... I wanted my best friend back.

To be continued.

Hope you enjoyed.

Question:
'Should Eren agree to save Yoko? or should he ignore her existence?'

- bye!
