Spoiler:
Okay so I thought the 20 first chapter is going to be okay but then when I read the 30th chapter. The black haired girl whom I thought is kind. She is a fucking user and total sadist with a problem on her personality. Same with the leading guy. That MC is a fucking sadist who cheats to her girlfriend and abuse her. While he totally wants to be a masochist to that sadist black haired girl.
While this girl with glasses who tries her best to be a masochist for his fucking bf doenst have any clue on whats happening between his bf and BFF(black haired girl). His brother even mad at her for seeing the bruises on her body.
I hope she would see the truth. And also hoping that the brother would fucking kill the MC.

It was really good on the first 20 chapters but then again on the 30th chapter it is going to be messy. I dont exactly know what the MC and black haired girl always talk about. But I think the black haired girl tries to convice the MC to show its true self(being sadist) by seducing him. And this shit is falling to that Black haired girl.
When did Hori san became a tsundere?! tssssssk.
