Mizurumi's manga / #College(22)

I have the book and all, but still made me confuse about some stories, then again at the end I understand it because of going through all the pages. This tankoubon(compiled book) is consist of 3 stories. 1st about Shinobu and Eichii, 2nd Son x young father(>////<), and third is about the 4-eyed dude XD

A popular semen x a plain uke

Tamenaga, having troubles with his looks encountered a younger guy who has taken a liking with him name Tamotsu

There are two stories. But the other one doesn't have a good ending.
