These kinds of stories can get kinda tiresome, the female trying to seduce guys for reasons i mean. This heroine is actually really nice however. She's being active and while some may call her avoiding stuff caused by things she won't do anymore stupid, its perfectly reasonable given that she has yet to know if this world runs on rails.
Basically even if SHE keeps clean someone else might do it and she might still be blamed. Depending on the view point she might actually be an innocent character from the start who was never directly shown to be doing anything wrong. We didn't play the game so we can't know. The point is that she is being bullied right now and she needs to show strength to avoid being looked at in such a light.
