So.. does every main characters in this manga treat this girl better that she treats them? Like for real main heroine and boy (and possibly the other friends) treat this girl better than she treats them which is slightly maddening.
Also this girl is in love with self-destructing. Look, life is hard, that's a fact. But she is actually not doing anything to better herself or her situation. All she's telling us is that everything she's tries has failed and that's she's quitting. Like, girl, if what you're currently doing isn't working then try something else, stop with this starting and quitting bull crap you're not getting anywhere with that which why you're currently stuck in your current predicament.
