A total of 63 students from the performing arts class at XX University traveled through time on their way to class.
No. 42: I knew I shouldn't take this class.
No. 28 (Monitor): If you miss class again, you will fail the class.
[The settings of universities and performing arts classes are fictitious. There are 63 protagonists. I tried my best to write them as group portraits]
Lightning protection:
There are many private settings, including Wen Ye, Ming Ke, Fu Hui, Demon Slayer, and Harry Potter.
This is a big idea, I don't know when I will write it
Concept: Mainly to have fun mixed with some plot
