The heroine Song Ci was forced to marry Gu Yesi, the heir to a wealthy family who was rumored to be dead, in order to celebrate her sister's wedding and get a huge gift to treat her mother. On their wedding night, she was horrified to find the "body" sitting up from the coffin. It turned out that Gu Yesi was a supernatural being who was imprisoned by the family due to his special constitution and needed to be "nurtured" and suppressed by someone with a specific destiny. The two signed a secret contract: she played Mrs. Gu, and he paid a sky-high "suppression fee." As they got along, Song Ci discovered that although Gu Yeci looked lazy and arrogant, he always silently protected her when she encountered supernatural events. Under Song Ci's money-obsessed heart, there is a sensitive and fragile heart caused by poverty and family pressure. She used the resources of the Gu family to make crazy money, and also used her unique "suppression" ability to help Gu Yesi resolve crisis after crisis from supernatural forces within the family and outside. When the contract is about to expire, a bigger conspiracy hidden behind the substitute marriage and related to the lives of the two people comes to light. Song Ci is shocked to realize that he is no longer a stand-in who is greedy for money, but the only salvation and weakness of the sunny "cat-like" ghost husband.
