It's so funny that Xu Yao, who Gu Jingyi owed 15 yuan to, was transferred to his class!
In the office:
Director Yan: Jing Yi, if Xu Yao sits next to you, it won't disturb your study, right?
Gu Jingyi: Teacher, I am being called for debt every day. Please change my deskmate.
Director Yan:? ? ?
Gu Jingyi: I owe him 15, and now I pay interest day by day.
Director Yan: That's great. I think you two are a good match. Don't change.
*Can't write knife, only sweet* (I guess so?)
Intention: Maybe if I owe a debt, I can meet my husband!
