Lu Tingchen, the heir to the top wealthy family in City A, is a feared "cold-faced king of hell" in the business world. However, on a rainy night, he offered Su Wanwan, an ordinary college student, a contract marriage contract - three years of marriage in exchange for the sky-high price of her brother's leukemia surgery.
In order to save her loved ones, Su Wanwan signed an unequal agreement and stepped from a poor school into the luxurious but cold world of the wealthy. She thought this was just a deal where each got what he wanted, but unexpectedly, her married life overturned all her expectations: Lu Tingchen, who seemed cold and indifferent, would strongly protect his wife when she was ridiculed by celebrities, would silently take care of her when she was in trouble, and even doted on her like a star.
Under the contract, suspicion and temptation are intertwined, and conspiracies and crises are hidden. When the childhood sweetheart Bai Yueguang presses closer and closer, when the secrets of the wealthy family gradually come to light, and when the feeling of "marriage first, love later" quietly grows, this marriage that started as a transaction has already deviated from the preset track.
Su Wanwan discovered that there was a shocking reversal behind Lu Tingchen's choice of her; and before she knew it, she had already fallen into his gentle trap. Slapping the money-loving ex in the face, tearing apart the vicious female supporting partner, and unlocking the group's pet buff, this ups and downs contract marriage will eventually bloom into the most touching love chapter amidst suspicion and protection.
