I remember that around the New Year we discussed about the meaning of "eating" in Chinese novel.
@Kokuto mentioned about XL's words in episode 5 then I rewatched that scene and saw the conversation between XL and XY when XL rested in WXL's room after he got injured.
Xiang Liu moved his lips and said silently: "I want to eat you."
Xiao Liu wiped it on his lips with dirty fingers, wiping it again and again, "You can eat me if you don't mind it being dirty!"
And in the next meeting, his first sentence to her is "have you bathed?". Haha, unfortunately, he just "ate" her at her neck.
