Dazai was... well... uh.. a good older brother.? except for how much he could tease and annoy you. sometimes he didn't know how to stop and hurt you a lot.. but he always apologized. after all, he loved you.

but the X-day has come for you. he found out your main secret, quite by accident. you were in love with his best friend... and now he knew it. he was standing in your room, not stopping teasing you.

"what did you like about chuuya? the fact that he's barely taller than you?"
