exaggerating things like Lu Yan's pupil and the captain is the usual way to go wild, but it's not ironic. It's just playing with the stalk, saying that the names given to children by parents nowadays are too grandiose, and the captain is just a small position in the school, just like: Hum, I'm the leader of the XX group of XX class in XX school, you'll wait and see, and things like that are just playing with the stalk.
Captain, it's not because of this episode that he became angry. Just visit more post bars.
