the brother was a morally gray indecisive person. he didn't have bad intentions, but he also didn't really have the best intentions in mind. it feels worse since BOTH brothers are dead and vince is the only one alive, both brothers whose deaths seem to be very unfortunate (yeon probably unalived himself, while mc probably died due to his weak health. side note: i feel very bitter if yeon actually unalived himself cuz i think he doesn't deserve making the people around him feel worse when he was the one who caused this situation anyways??? anyways..)... unfortunately, the mc's past revealing itself seems like it'll do more bad than good for both mc and vince... sad, but also necessary.
