Three years ago, in order to save her critically ill father, Lin Jia signed a marriage contract with business tycoon Lu Chen. He needs a wife to take care of the family, and she needs a life-saving money. The money and goods are both settled without interfering with each other.
For three years, they played the perfect couple—he was considerate in public, she was quiet and decent at home. They share a mansion but live in parallel worlds. Until the day before the contract expired, Lu Chen's Bai Yueguang Su Wan returned to China with a high profile, and the dazzling lipstick mark on the collar of his shirt became the last straw that broke the deal.
On the day of the divorce, Lin Jia calmly returned her wedding ring and prepared to leave the show completely. Lu Chen uncharacteristically grabbed her hand: "What if I don't want it to end?"
At this moment, Lin Jia discovered that the cup of black coffee she brewed for him every morning had already penetrated into his daily life without him noticing; those silent hours spent together in the study late at night had already left an indelible mark on each other's lives.
And when Lu Chen took out the new contract with no expiry date from the inner pocket of his suit, Su Wan's conspiracy really came to light - it turned out that the transaction three years ago was not just a transaction from the beginning.
"Mr. Lu, the contract has expired."
"Then sign another one. This time, there is no deadline."
This is a story about disguise and authenticity, transaction and sincerity. When a contract marriage encounters an unexpected heartbeat, and when a carefully planned exit is disrupted by an accident, how should they find their own answers between lies and truth?
