Her point is that her parents' neglect made her feel rejected/different since her situation wasn't the norm.
=> Since [m x m] isn't the norm either, she's afraid Haebom will end up in her situation too, so she's trying to separate them before that happens.
WHICH IS VERY STUPID BECAUSE, GIRL, SINCE YOU KNOW WHAT IT'S LIKE, SHOULDN'T YOU BE SUPPORTIVE ????
anyway<33 she believes her reality is the truth, sadly.
I get her flawed logic but it's still extremely flawed. But w all know she will understand later like idk she will see them smiling together and be like "maybe what's truely important is just having someone regardless if your alone cause they will always be by ur side" or something obvious like that
I didn't understand the girl's point...? Well, okay, I'm sorry your parents were so cruel to you but what does that have to do with you being homophobic? xD
