You're Dazai. 15 Soukoku.

Dazai had feelings for Chuuya. Dazai had always kept them secret, due to you knowing that he would deny and probably yell at him. Chuuya was oblivious to his flirting, and dissed it as teasing.

(One-sided Soukoku;; Dazai’s crush on Chuuya)

The two constantly bickered.. whether it was Dazai teasing Chuuya for his small height, or him getting all riled up easily.

You two were hanging out at the Arcade, again. “Dammit!! I was gonna win!! You cheater!!”
