Contains at least two stories in one volume.

1st story - Don't remember this one well.
2nd story - The uke's older brother (?) from the 1st story is a bartender. He somehow flashes back to his high school days when he used to bully this guy. Turns out this guy was actually pretty strong + good-looking all along and they ended up hitting off. The bartender was the uke and bullied guy was the seme btw.

Does this ring a bell anyone?
