In this short scene, Caixin introduces us to a new character named "Qi yibai" . She's a popular boxer in the boxing league, and she's also a good friend of Caixin's. Caixin tells her that he's coming for her, and that she better watch out because she'll be a "nightmare" if she doesn't get along with the other guys in the league. He tells her to be careful, because he'll catch her in a lie. He's not going to let her lie, though, and tells her she can try her luck at the game by entering the "demo" , which is a blind game where you pick a random character to play. This is a great opportunity for Caixin to get to know his new friend, and to see how he reacts to her.
