What a shitty brother. I hate when these people's shitty actions are enabled because the author can never have a character tell someone like this to fuck off.
@Jak For real, Shojo mangas in general are filled with this shitty tropes, these creepy dudes are always labeled as "flirty" or "cool" guys, it's so weird.
I don't know why I teared up at when the characters were crying. Maybe I just felt a lot of emotions at that time because I got a bad grade on my test haha....T_T
