In 2016, Chang Yue met Chen Ye, a transfer student. Through fate, Chang Yue fell in love with Chen Ye.
Later, Chang Yue died unexpectedly. Three years later, Chen also saw her diary on Chang Yue's memorial day. There were bits and pieces of her love for him in the diary. It's a pity that Chen Ye doesn't like Chang Yue, he just feels sorry for Xu Shiyi's affection.
"Separated by a wall, some people are the moon and the vast expanse of stars; while others are shadows and all living beings."
Concept: Not all secret loves can see the light of day.
