She should just leave the party, the supposed leader is an unstable, scummy, jealous, insecure, egotistical idiot that will either get her killed or try to rape her in the end. I hate girls like her, she has feelings for the MC, but never voiced them, probably expecting him to take the initiative. She also doesn't set clear enough boundaries for the trash leader that she obviously has no feelings for. Had she nipped that in the bud early on, he might not have fixated on her so hard and hated the MC even more, because he was already obviously jealous of him and has a huge inferiority complex. Please stop writing female characters so stupid, dependent, weak, and indecisive. Also, everyone, it's not the MC's crotch that's lighting up, it's his fucking hand, you damn children. The last panel even clearly and blatantly says "A LIGHT SHINING IN YOUR HAND".
