If the lover you reunite with is a carefully disguised version of yourself, is this love true or false?
When she was eighteen years old, Jiang Wanqing personally untied the bow on Fu Chengyu's wrist at a "blind date party" arranged by her family. Two top students wearing perfect masks secretly fell in love outside of the script. However, after the college entrance examination, one went overseas and the other stayed at home. For eight years, there was no news.
At the age of twenty-eight, she is already a calm and professional cardiac surgeon and is about to enter a stable marriage. On a rainy night, she "picked up" "Xiao Zimu" who claimed to have lost his memory in the emergency room - he was wild, sweet, and all he saw was her, but he had a strikingly similar profile to Fu Chengyu, the helmsman of the Fu family who forced her to a desperate situation in the mall.
From then on, her world was divided: during the day, he was the cold and distant "Mr. Fu"; at night, he was the enthusiastic and straightforward "Xiao Zimu", forcefully intruding into her life and using the heat she had never experienced to pry open her dusty heart.
When the romance weaved by lies reaches its peak, the truth suddenly arrives - it turns out that this grand reunion is a desperate move in the name of love. It is the craziest and most fragile true self he presents after stripping off all social identities.
Jiang Wanqing must make a choice: embrace the scarred soul that created a substitute for her, or turn around and move towards the planned stable life?
A "substitute game" that begins with a bow tie, an ultimate adventure about sincerity and disguise, responsibility and self, is about to kick off.
