Ryan and Michael Chen are classmates of Grade 04 Performance Class of Shanghai Theatre Academy. Other students in the same class are: Kimi, Hailu, Harper, Sunny, Lan Yan, Fu Yu, Guangxu, Sun, Yan, Ryan, Huang Ge,,,, Zhang Dianlun, Jiang Shuying, Eric Wang and Chen Rong.

In the previous "Daddy Comes Back", Du Jiang once participated in a talk show with Mm-hmm and became the surprise guest of Ryan, the protagonist of this issue. This also makes people know that Du Jiang, Ryan and Chen He in the men's running group are college classmates.

On the same day, Ryan also went backstage to visit Uh-huh, but Uh-huh, who just woke up at that time, refused to go near Ryan, which made the "charming little cheetah" hit a rebuff.
