In order to save her seriously ill father, Lin Yue mustered up the courage to find Gu Mingcheng, the president of the Gu Group, and proposed to sign a one-year marriage contract. She only needed five million, and Gu Mingcheng just needed a wife who would not pester him to cope with the pressure of family marriage. The two hit it off immediately and began a contractual marriage in which each got what he wanted.
However, as time went by, the originally cold contractual relationship gradually changed. Lin Yue's tenacity and kindness slowly melted Gu Mingcheng's cold shell, and Gu Mingcheng's gentleness and thoughtfulness also made Lin Yue begin to waver. As the two got along day and night, they gradually developed sincere feelings.
But this relationship has not been smooth sailing. Gu Mingcheng's family, business rivals, and hidden conspiracies have all brought many tests to their relationship. Lin Yue not only has to face pressure from the outside world, but also unlocks the secrets deep in Gu Mingcheng's heart. In the process of protecting Lin Yue, Gu Mingcheng gradually realized her importance to him.
When the contract is about to expire, both of them are faced with a choice: continue this false marriage, or bravely face the true relationship? In the game between interests and true love, can they find true happiness?
