Why did Melosin call that villette dad?

Excuse me, do you want to ask the question "why does Meloshin call that villette dad"? This is because the former wants to show respect to the latter.

So villette and Melosin are both characters in the game Genshin Impact. Na villette, the highest judge and water dragon king in Feng Dan, is famous for his impeccable "justice"; Meruxin, an indigenous resident of Harmo Village. Beauty house Xin is a family of hoses, and villette helped beauty house Xin to integrate into human society, so beauty house respectfully called villette "Dad".

Genshin Impact is an open world adventure RPG developed by Mihayou. Players will explore a fantasy world called "Tiwat" in the game.
