BB shippers often shit on Sun. BS shippers seldom shit on Yang (in fact I've never seen it). I don't mean legitimate criticism of character but "he's an abusive stalker fuckboi who should die in a ditch"
Yeah that is true. It’s probably because they know it disrupts their ship as he is Blake’s love interest, Yang is just a supportive friend that’s part of her team and their relationship has not been established to be about something more or even show mutual attraction, whereas Sun and Blake have.
