After her mother died mysteriously, Su Wan was used as a bargaining chip by her biological father, Su Zhenhai, and was forced to marry his business rival Lu Shiyan. This contract marriage, which began as a conspiracy, gradually deteriorated as the two got along day and night: Lu Shiyan's cold shell hid his protective desire for Su Wan, and Su Wan also wavered under Lu Shiyan's "special care". However, Su Zhenhai's constant pressure, Lin Weiwei's provocation, the mysterious clues left by his mother, and the connection between Lu's father's death and the Su family turned this marriage into a cage full of dangers. Su Wan has to protect himself in the whirlpool of a wealthy family while also uncovering the truth about his mother's death, while Lu Shiyan struggles between family hatred and love for Su Wan. When the mask of the contract was torn apart, the two broke through numerous obstacles and found each other's salvation.
