People like assuming common character tropes whenever they see a character but it's obvious there's more to it then that. MC is fuckboy scum but that's because of his PTSD and because of that he cares about his girls. The crazy yandere bitch doesn't actually go around killing everyone who interacts with her fuckboi-kun and just zealously listens to his "desires" instead, albeit interpreting them in her crazy yandere way. but I guess I have a soft spot for evil-portrayed mcs getting fucked by circumstances though.
