one of the reasons I'm so fascinated by #mobing is, like. Luo Binghe is basically raised completely disconnected from his demonic heritage, especially when he's young, thinking of himself as a human. And then there's the rupture, both in PIDW and in #SVSSS where he's like "Fine, then, if humanity doesn't want me, I'll be a demon!"
Only, of course, he doesn't really have any idea what that means. And although it's never explicitly stated, it seems like MBJ is his guide to demonic culture.
