Maybe Bisexual???
Note that the blonde is craving for affection so when the fl said she loved him, his heart already set to not let go of that. It's not a matter of gay or bisexual but individual who shows him affection first. And for the step brother, it was said that he's obsessed and possessive so when the fl said she wanted to leave him, he doesn't like it cuz in his mind the fl would always be obsessed with him and not go for another so yeah...lol
Ooooo that explains everything thanks you

The art style is pretty but why does it has to become straight isn't he original a gay guy how did he turn to straight ╥﹏╥
