In a school canteen in the mountains of China, a group of siblings is eating a spicy snack known as tiao . Sibling X says that he's going to give his best friend, xiang ling, the ten packets he just bought. He's worried that he and his brother are weird, and he wants to warn chenglan not to come near him again. Worried that she's trying to threaten him, he tells her not to do it, but to ask him first. He wants to know if she can deal with the spicy food, and if she doesn't listen to him, then he'll have to stop her. She's a despicable girl, he says, and she should be ashamed of herself for using such a dirty tactic. She has to ask first, and then she'll be able to teach him how to act like a real person, and not just a martial artist. .
