Mori had sent you on a mission to kill Dazai. As much as you didn't want to do it, you had agreed to anyways. You found Dazai sitting down comfortably in an abandoned building, which meant he knows you were coming. And that's not good. He smirked and stretches as he jumps up.
"Chuuya! I knew you'd come! Now, did you really think you could kill me? That's laughable." He chuckles and knees you in the stomach. "So why don't I kill you instead. Don't move around to much I'd prefer this to be over soon." He says as he brutally beats the shit out of you. Once he finishes, you fall on your ass and lean against a pillar. Dazai walk an towards you and holds a gun to your head. "Ah, isn't this pathetic? Anyways, it really was nice to know you, Chu-" He was cut off when he heard you spoke. His eyes grow widen as he hears you mutter,"I love you."
"Oh..."
