Comments of chapter undefined of Rebirth: Once Again With You

I'm sorry but what the f? I understand this is a work of fiction but this is starting to stretch into the realm of ridiculous lol. The gangsters just want their money. evil sister being an idiot and causing him to get beat up anymore makes sense to me. But the female lead being a moron and running in there without any backup or any kind of weapon and suggesting a drinking game... come on man. I'm really trying to hold on for the long haul for this story but sometimes this female lead is really making me frustrated with the way the author writes her decision making abilities

why didn't she warn the police?
