Chapters 1-4 follow the sweet relationship between Shibata Yuzuru, a 181cm uke, and his 172cm lover Yogi Issei.

This manga follows Oyama Yumeji, on his quest to cure his impotence. Enter Shinkai Seiji, a shorter, younger man who has his eyes on making Yumeji his uke.

The story follows Yuuta, who is constantly bothered with taking care of the short, cat-like Madoka.

Chapter 1 is pretty messed up imo, but the main character is the seme and is much shorter, and I presume younger, than the uke.
