The Shen family has a century-old legacy. Once the head of the family suddenly passed away, he left behind a huge inheritance and a will that pushed everyone into the abyss. In order to stabilize the shaky family empire, the eldest son Shen Yanzhou was forced to sign a one-year "contract marriage" with the daughter of his enemy, a woman he hated extremely. It was originally a cold transaction in which each got what he wanted. The two drew boundaries in the mansion and faced each other tit for tat. However, when the wolves and tigers within the group tore off the disguise, and when the dust-laden secrets crushed family ties into powder, the fake show gradually got out of control. She is the most annoying piece on his chessboard, but she is also the only "accomplice" in his desperate situation. When true love grows in calculation and betrayal, they realize that the most gnawing thing is not hatred, but the body temperature that they have to get close to under the contract.
