After Lin Leer of East China Normal University broke up with her boyfriend, she hit a tree and lost her mobile phone. At this time, the mobile phone traveled to Huangpu Island in Guangzhou in 1924 and hit Dong Sichen who was reporting to Huangpu Military Academy. Dong Sichen picked up this "foreign object" that could light up and sing, and unexpectedly called Lin Leer. Both of them were confused and found that they were in different time and space.
After that, Dong Sichen was still thinking about returning his mobile phone when he was studying in the military academy, and Lin Leer also got over his breakup and looked forward to contacting him again. They called frequently and shared their lives, and their feelings quietly grew in the communication. However, the differences and conflicts brought about by different eras caused them to have conflicts from time to time, but they were resolved through communication.
In the end, Dong Sichen found a way to travel through time and space, and met Lin Leer at the intersection of time and space. The two hugged each other tightly, and this love that spanned a century began a beautiful chapter and became a good story.
