you (Dazai) and chuuya nearly hate each other. But your classmates found that hilarious, and ship both of you. Chuuya hates that, but you also find it silly and keep teasing him about that. Chuuya is a bully, but you are just a chill guy. Chuuya is often trying to get under your skin but every time happens the opposite.

Today was a free day at school, and whole class decided to play TRUTH or DARE. And it was your turn to tell chuuya t/d.

"I choose dare." Said chuuya.
