Tell us what happened to her bully. She is the biggest victim. Stop pretending you didn't write those chapters.
I've been wondering about it for chapters way way before but dont keep your hopes up, with what happened that night and betrayed by her "friends" in school right after, i doubt she'll ever leave the house, let alone trust anyone to try and build new connections
At best? She and her family moves out to try and slowly get her back on her feet on a new place, with her scarred for life to be an anxious scared wreck (hinted by a non canon off hand joke panel)
At worst? She cant handle it anymore and just ends it, considering how dark the writing is earlier in this manga, the parents or school (or both) tries to hush it up due to social stigma, shame and in case of the school, to avoid scandal (she is last seen in school running away in tears after all.)
