Le Ran has a secret. She and her previous life Le Jingyi can penetrate each other's bodies by sleeping at the same time. Fortunately, after mastering the rules, it did not affect the lives of both parties very much. Instead, they began to use the asymmetry of time and space to help each other.
Le Jingyi can use an ancient song to help Le Ran win the guzheng competition championship, and Le Ran can also help Le Jingyi use portraits to attract the attention of superiors and get rid of the fate of drifting with the crowd.
The two sides' lives in their respective time and space were not satisfactory, but they flourished in the other's time and space. But even so, Le Ran never thought that one day, he would stay in the time and space that belonged to Le Jingyi forever.
In short, it's a story about two girls who couldn't get along in their respective eras, but became prosperous after exchanging identities.
