"If you could become an idol one day, what would you do?" Lin Xiaoxia never thought that this joke among fans would come true.
One rainy night, she was hit by lights at idol Zhou Xingchen's concert. After waking up, she was horrified to find that the face reflected in the mirror was the face she saw on her phone wallpaper every day - she had become Zhou Xingchen! But the real idol is currently in her small rental house, gaping at her ordinary body.
This weird "soul exchange" happens at midnight every day and lasts for 24 hours. During the day, Xiao Xia has to deal with a busy schedule, the tricky media, and the insider secrets that she could only see on the screen; at night, the real Zhou Xingchen has to endure her boring social life.
When Xiaoxia discovered that Zhou Xingchen's perfect persona was caused by depression controlled by drugs and ruthless oppression by the agency, she decided not to be just a bystander anymore. With her fans' knowledge of her idol, she started a thrilling double-sided game: using Zhou Xingchen's identity to fight against the dark rules of the entertainment industry during the day, and using her own identity at night to find a way to break the curse.
But the biggest crisis is - as the number of exchanges increases, they begin to share memories and emotions. When you can't tell whether your heartbeat comes from your own or the other person's feelings, how should this taboo relationship end?
