Fan girl's manga / #dark story(2)

Yashiro has ...issues (more like a whole damn subscription). He's a masochist with slightly sadistic tendencies who gets off more with guys. Otherwise he's your average high school student. Recently though, there's been this annoying classmate Kageyama. Already included in vol 1 of "Saezuru Tori wa Habatakanai" -

The masochistic, lewd and beautiful yakuza Yashiro and his silent, clumsy, impotent subordinate, Doumeki. This is the story of a man who has never known happiness and of a man who is reborn by getting to know him.
