Tsundere

I kid you not, i forgot the uke's name for the longest time. All i know him as is "senpai" and the seme as "morinaga." Beyond that, nothing.
But yeah, cute story. I can still reread it many times.
senpai is so fucking tsun, i love it.

"It's not like i got these injuries from protecting you guys or anything"

He won't admit to his sister that he loves her. I totally thought it was in an incest way at first but that's probably because i'm an idiot.
