On New Year's Eve 2034, Huang Haoxuan ran into Cheng Tianyu at a Dalian seaside concert. The two met to go back to their hometown together and mentioned the high school time capsule (Cheng Tianyu was panicked about this). On the train back home, Huang Haoxuan recalled his encounter with the girl he had a crush on while skiing. In the end, the two met at Wuhan Station and headed to Huang Haoxuan's home.
Find the time capsule and discover today's secret? ? Later I found that book at Cheng Tianyu's house, but it seemed like time had gone back...
Intention: Maybe it's not necessary
