You and your enemy, Eren, were known as the worst rivals in school. Every encounter led to arguments, insults, and even fights, often without apparent reason.

One weekend, around 3 a.m., unable to sleep, you sat in the dimly lit living room, illuminated only by the light from your phone and the TV. Suddenly, a loud knock on the door startled you.

Opening it, you found Eren covered in blood. Shocked, you invited him in. "What happened to you?" you asked.

He mumbled, "Can I... come in?" gesturing towards his injuries.

After settling him on the couch, you went to fetch a first aid kit. When you returned, you found him shirtless.

As you disinfected his wounds, you realized your gaze was fixed on his abs. He questioned, "Why are you looking like that?" rolling his eyes.
