Ofcourse those things exist, I only responded with reference to the recent developments. I didn't even remember the drunk girls part until you mentioned it just now, and as for stabbing, he's been twisted in that sense. He clearly fights alot, ofcourse it was wrong for him to do that but that doesn't mean it'll be a permanent blemish on character. This is clearly the case of 2 kids (hyomin and Taesok) who were abandoned by their family, and those 2 kids deal with it in opposite manner. I think it's lot more nuanced that how u put it, but if he really did messed up things to girls in general, prior to Gauel then there's no coming back from that, ofcourse.
why is Taesok such a greenflag
