The fox spirit Chang Bai says she likes him, that monk. She doesn't care about all those rules and precepts. She's a demon, and that's her license to ignore the human world.
The monk Yuan Xiu says the scar burned into his scalp was the price he paid. He still remembers how much it hurt. "So that's why you won't return to lay life?" "Yes. I can't bear to let my hair grow back and cover it." What a flimsy excuse, so flimsy that even Yuan Xiu himself refuses to believe it, so flimsy that anyone could hear he was talking nonsense. But Chang Bai isn't human, so she believes him. That's just as well. This way, she won't see through how he's hiding his feelings for her.
It's very interesting. Please keep writing.
