Hero Heel
Sawada is such a douche, Katagiri would be a better choice. But since you can't choose who you fall in love, I kinda understand Minami to choose Sawada.

Sleeps around slutty (future) seme
Akuma Wa Hohoemu
Hah, I knew it! Shou's been sleeping around the entire time. (Expected this ever since I read Kawaii Akuma) Most of Sensei's stories feature slutty semes and innocent/sweet ukes. I guess abstinence is impossible for those who say they're in love, but not for those who are their unrequited love, like Itoshi no Nekokke or Complex. Substitutes are needed for their lust right? No pure one-sided love virgin in this world.
Yukimura-sensei To Kei-kun
Felt like I was reading Links, but more confusing and less pairing. It's like it's there, but not yet there.
Orangenia na Hibi
The last story's uke,Rui, was getting on my nerves. What a masochist! Mikami is just a cheating slut, why does he want to stay? Cause of love? I don't get it at all. Ah! I see...the other masochist, but a seme, is in here: Pochi no Shiawase, http://www.mangago.me/read-manga/pochi_no_shiawase/ - story of one of Mikami's sex partners. Another partner for Mikami here: http://www.mangago.me/read-manga/aisareru_hito_e_tsugu/...what a busy guy!
