Bokura ni Namae wo Tsukerunara
Read: Ch.8 Incest: They‘re blood-related brothers, but their parents got divorced and separated them in elementary school. Actually more fluff than I‘ve expected for this one. Seme isn‘t sleeping around, just staying with some other friends overnight to avoid uke. But he was a playboy before seeing uke with his bf and realising his feelings for his brother in middle school.
Otona wo Komaraserun ja Arimasen!
Read: Ch.2 Student seme x dorm manager uke. Niyama-sensei again, beautiful and fluffy. Def. re-read, love it!
My Roommate Obsesses Over Me
Read: Ch.18 Super short chapters and very fast pace. It ended so quick, like a speedrun, and was kinda over-dramatic. Seme has been in love with uke since childhood and confesses to him upon meeting again. He‘s trying to woo him and only has eyes for uke.
Mukai no Heya no Neko
Read: Ch. 10 Pretty good story with nice character designs: Uke is a shy college student and in love with playboy seme, who lives across the dormitory hall. Then seme misunderstands that uke is actually in love with his roommate and tries to help out, but during that he slowly falls for uke til he can‘t take it no more and confesses. Even though seme‘s a total playboy having a new gf every few months due to his loneliness, it‘s still pretty nice, since the misunderstanding of uke being in love with someone else adds a lot to seme‘s jealousy and feeling rejected. Not into playboy stories, but this one‘s turned out really well.
