Apocalypse in Another Universe

The characters from AOUAD end up in KM's world. They start going to school with her and she's the only one in her school who has seen AOUAD. She befriends them and shows them what she knows. She also tells Gwi-Nam she won't let him pull any of those stunts he did in their universe and that since the science teacher is here she fears that he may make the virus here. She keeps a close eye on Jinsu who she has already befriended and makes him part of Cheong-San's friend group which she is a part of. She also keeps Gwi-Nam and the others on a very tight leash with the help of Su-hyeok and the guys. Unfortunately Myeong-hwan and his two other lackeys befriend her school's bullies. Gwi-Nam has started hanging around her and the others and stopped bullying people becoming close to KM, Cheong-San, and Su-hyeok.
Of course one of the bullies has been harassing KM and is absolutely obsessed with her hating how close and touchy she is with the guys specifically Cheong-San, Su-hyeok, and Gwi-Nam. Cheong-San and Su-hyeok started dating before they came to her world and not long after Gwi-Nam started hanging out with them he joined the relationship. They want her to join and soon learn about her harassment. They become EXTREMELY protective of her and once the apocalypse starts they are a bit overprotective of her. Lots of her classmates that she calls friends (not close are anything but close enough to be called friends) die and there are more hambies this go round than there ever were before. The bullies become hambies and one's only goal is to make KM his.
