At the 36-year-old birthday party, Wang Qi drank too much. In his dream, he returned to the high school campus twenty years ago. There are Xu Xiaobin, who is "good brave", Zhang Shuo, "aristocratic school grass", Liu Yu, "greedy and greedy", Liu Yi, the first love goddess, and Liu Shuang, who is harmless. Time flies, memories become stronger, and Wang Qi thinks about them.
Unfortunately the movie Sudden Youth is not yet available on HBO Max.
