- They're kids
That helps understand where she's coming from but it doesn't make her sympathetic.
Yep, they're kids. That's why I feel a bit bad for her. But I still can't really sympathize with how stupid she is acting.
It seems like you two are confusing sympathy with empathy perhaps? You don't have to agree with or even understand a person to sympathize with them, but you two seem to already be sympathizing with her from your comments.
Face the problem. Talk to Amane and tell her the truth.
She's a child who's been through emotional abuse and has some deep seated insecurities. Dialogue between two people is quick to become a very emotionally charged activity. Randomly bringing up a topic that has deep ties to her emotional trauma that she doesn't even understand and trying to talk through it between two middle schoolers who have no relationship experience and probably very minimal communication skills... Something tells me that one's a long shot...
Get someone to help her get over her complex / psychological issue.
That would probably actually help if great mental health support was that easy to come by.
Or maybe just tell the people who told her she shouldn't smile to fuck off.
That's just plain horrible advice.
The one person she shouldn't have hurt was Amane who was a total sweetheart to her.
Agreed. That seems to be one of the things she was trying to minimize, but at the very least she could have handled the break up much better, while she gave herself some time to sort things out. But again, she was a middle school girl with no relationship experience and minimal communication skills. Hopefully Kou can point her towards a better track.
