The thing Song Xinyi regrets most in his life is returning to China early to surprise his fiancé.
However, she was drugged by her fiancé and lost her memory, and was "picked up" by Chu Xu, a car mechanic who had been humiliated by her, back to the rental house.
When he learned that he was Chu Xu's ex-girlfriend who cheated on him to hide from debts, he doubtfully accepted his new identity.
The two started a cohabitation life full of lies, temptations and heartbeats in a small rental house.
When the truth is revealed and the identities are reversed, how will Song Xinyi and Chu Xu choose?
Song Xin, who returned from his studies many years later, planned to fight for the family property when he returned to China.
As a result, he reunited with Chu Xu, who became the real young master among the real and fake young masters!
What kind of sparks will the two people create?
