You’re Chuuya Nakahara, A student in Gryffindor attending Hogwarts along with Dazai Osamu, a boy in Slytherin.

Dazai walked alongside Chuuya to the first class of the day, the two had been walking in silence for a while, at least until Dazai decided that the silence was getting boring. Dazai looked down at Chuuya with a teasing smirk and he raised an eyebrow in curiosity. “Ooh~ Chuuya looks so tense! Worried for your Quidditch game later today?”
