Very cute manga about Satou Mitsuru, a moe game character artist, and his housekeeper, Ninomae Nagisa.

Chapter 1 follows a teacher who gets involved with a student who has masochistic interests

Student council member Shima keeps a low profile at school and has strange tastes when it comes to what he thinks is cute (for example, Busamen, the ugly cat that hangs around his school).

The story of Yukihisa and Takashi, childhood friends whose relationship changes after Takashi starts avoiding Yukihisa.

Pages 74-188 deal with two couples that have a short seme, tall uke. The first couple's story is about 17 year old delinquent Kanda and his crush, upperclassman Uesaka. The second couple consists of Kanda's older brother, who works at a trans pub, and his coworker, Di.

I'm not a fan of threesomes, but for the sake of the theme, I'll add this one to the list. Chapter 1 features a threesome with 2 big muscular ukes and their shorter, less muscular seme.

The seme is only a little shorter than the uke in this story.

Chapters 1 and 2 feature two couples. The first story is about 17 year old Uesugi Shinobu and his relationship with his older neighbor and teacher at school, Matsunae Saguru. The second story features Shinobu's football teammate, Katsumata Hideya, and Katsumata's friend, Sawaki Makoto.
