Ok, I read this story a long time ago. It's about brothers (I think) the uke was in school and the parents were away and the big brother was taking care of him. I think the uke was in middle school? maybe high school? That is as far as I remember.. sorry if it's not much.
Not sure, just pick some up 4U to check.

I'm looking for a manga I read a couple of months ago. I remember the characters are super thin. They met at college and they were at the same middle school. The seme asks for forgiveness in the library. That's as much I remember. TIA
