22-Year-old Shen Yi is the most professional "emotional stand-in" in the Performance Department of the Academy of Drama - clearly marked with a price, he plays the role of the lost person for the client and completes the farewell ceremony.
She has only one professional credo: avatar is for the living to let go, not for the living to indulge.
Until Gu Yanzhi, an upstart in science and technology, offered her a sky-high price and asked her to play his fiancée Su Nian who died in a car accident for a long time.
Shen Yi accepted the commission, only to find that what Gu Yanzhi loved was not the real Su Nian at all - but the perfect phantom in his imagination.
What's even more ironic is that the real Su Nian was trying to escape from him during his lifetime.
When the stand-in begins to teach his employer how to love, and when Bai Yueguang is no longer a perfect symbol, Shen Yi must answer a question:
Is she pretending to be someone else, or is she borrowing someone else's shell to live out her life?
——This is a story about substitutes, truth and learning to love again.
