Pretty sure if someone called someone else a slut to their face they wouldn’t decide to make cookies together afterward. I hate how forced everything in this feels and how trapped the characters are in the premise of the manga.
@Hexador: You'd be surprised at the power of forgiveness. Most people would be like that, I agree, but I know people who let it roll of them like water off a duck and still be pleasant. "Ahh, it was just the heat of the moment. I know they didn't mean that!" I know this because I'm related to such a woman.
BUT!! In this case, I think it's more like because she needed the help and went to a club for it, she pushed aside her negative feelings so the job can get done.
