Ha ha ha, my mind was on that manga about the insane girl who this baseball player starts dating. If I recall, redemption arcs in that manga include "That time she sicked criminal punks to rape a girl who bullied her" and then ends up with one of her male friends she guilted into doing the raping going to jail for her.
Overall, different levels of interpersonal conflict and different stories. The level of bullying and conflict in this manga would fit perfectly fine in a Folkist play about people in a community having conflict and then resolving their issues, coming back together. The other is basically your standard extremely negative soap opera.
