It’s not his brother, it’s his other personality.
His second personality depends on the host, Naoya, so he needs to keep him alive. (If you remember Naoya tried to kill himself after the mc rejected him). So the second personality came to the conclusion that if the mc dates Naoya, he’ll be happy and stay alive

its kinda interesting but the fact that, that guy threatens the guy just to go out with his brother i mean the reason is really reasonable but no-
