Nikushoku Danshi to Soshoku Danshi
Hm, so two guys are stepbrothers and live with each other while they go to college. The blonde one hides behind his glasses to avoid being stared at because of his pretty eyes. The darker haired, slightly older guy dotes on his younger brother and has been secretly attracted to him for quite some time.

I really like the characters! Pure-hearted and virginal, but playboy looking student and the upstanding acting but actually sadistic tease student become unexpected stepbrothers. They can't let anyone know though, because their "fans" would freak out. However, the sadistic student starts making the moves on the playboy student and the playboy is confused that he doesn't hate it.

Overall I liked this story. Yuuto has been in love with his older stepbrother for ages, realizing it when he’s in middle school and walks in on his brother making out with another guy. When he can he moves to a dorm for college, hoping to escape his feelings. But he ends up rooming with his step brother anyway and constantly has to struggle to hide his true feelings. I didn’t like the older stepbrother much, he was too stone-faced, so much so that it didn’t feel real when he finally revealed his feelings. Also, the endless amount of unrequited pining hurt my heart, for real!
Sawareru Taion
ok, but the art style is very old-school yaoi. It's about a guy who suddenly becomes stepbrothers with a professor he has a crush on. They start living together and the stepbrother gives him a strict curfew.
