Lu Tingyuan, the president of the Lu Group, the top tycoon in Lin City, is well-known in the business world for his coldness, ruthlessness, and strong desire for control. There has never been a word "out of control" in his world until he met Su Wan, a designer whose family was in decline. In order to deal with the family's forced marriage and the trap of business marriage, Lu Tingyuan offered a one-year contractual marriage agreement to Su Wan, who was desperate. The terms of the agreement were cold-blooded, but there were exceptions that he was not aware of. In order to save her seriously ill father, Su Wan gritted her teeth and signed this cold contract, moved into Lu Tingyuan's heavily guarded villa, and became the nominal "Mrs. Lu".
In their cohabitation life, Lu Tingyuan's strength and Su Wan's stubbornness kept colliding. He was used to controlling everything with orders, but he made exceptions due to her repeated resistance and persistence. She was disgusted by his cold calculations, but was disturbed by his calm protection. When the conspiracy of business rivals, the opposition of the family, and the appearance of a gentle male supporting actor followed one after another, this contract that began with profit began to shake. Lu Tingyuan watched Su Wan get hurt because of him, and was shocked to realize that this seemingly weak woman had already occupied his territory and broke all his rules. He began to learn to let go of control and approach awkwardly, while Su Wan was also struggling on the edge of lies and sincerity - when the contract expires, will she be able to escape unscathed? Can this marriage that starts with interests finally blossom into true love amid out-of-control emotions?
