There's fuckin witches in Teyvat? Okay, sure. What the hell kind of milieu do they have going on over there. And uh, well, presumably Wet Justice wouldn't be talking about it publicly if it was a secret, so he's just going to operate on the assumption that telling this guy is fine and he's not going to get pancaked about it. "That sounds like, uh, a lot? Back where... I come from..." most recently, anyway, "There's just like, uh, there was the ascension of the new Demon Emperor and the downfall of the Old Palace Master as a sect leader. So just like... politics stuff." Thankfully. No merging of the realms! Thanks for enchanting the protagonist's dick with your weird tsundere charms, Cucumber-bro, even if Bingmei is creepy he prefers living in an un-merged world where there aren't horrible death chasms and lava and abyss monsters and shit everywhere! And where he actually has to commute to the demon realm!

Goddamnit he's probably blushing more now that attention has been called to it. But, well. It's not a secret. "Casper is, um. My. Boyfriend?" His voice goes up into an awkward squeak again.

"A demigod is, um. His mother was a goddess, but not his father. So he's sort of... half a god?" Casper told Ice Duke more than that, so that's presumably also safe to say.
