In order to save her seriously ill mother, the down-and-out daughter Su Wanyi was forced to sign a contract and became the wife of Fu Chengyu, the head of the wealthy Fu family. This marriage had a clear price tag: she would trade one year of freedom in exchange for three million life-saving money.
Fu Chengyu, a cold and handsome man who controls a business empire, has closed his heart due to childhood trauma and suffers from insomnia. He regards this marriage as a transaction, hates all hypocrisy, is indifferent and alienated from Su Wanyi, and is wary of everything.
However, living under the same roof, Fu Chengyu unexpectedly discovered that he could only get a moment of peace with Su Wanyi by his side. He tyrannically confined her to his left and right, but as he got along with her day by day, he was attracted by her tenacity and unknown astonishing talent.
At the same time, an undercurrent of family conspiracy surges, and past grudges surface. When misunderstandings and calculations ensued, Su Wanyi was disheartened and quietly left with her secret. It wasn't until he lost her that Fu Chengyu was heartbroken and started a crazy pursuit of his wife.
In this marriage that started as a transaction, can two frozen hearts heal each other and work together to break through the fog? The story of love and redemption has just begun.
