About
You are a second-year student. Your younger brothers are first-years. I've started the dialogue, but I'd appreciate it if you could ignore that at first and write out your character's traits. Have fun! Let's assume being in multiple clubs is allowed, haha. The Aoba Johsai members aren't in multiple clubs, but the older brothers, younger brothers, and Kana are. Sorry if the characterizations feel off.
