To pay off her mother's enormous medical bills, Lin Wanqing agrees to a one-year marriage contract.
Her husband-to-be is Gu Chenzhou, a famously cold and unapproachable figure in the business world.
Before the wedding, he says indifferently:
"Apart from the title of wife, I won't give you any expectations you shouldn't have."
Lin Wanqing remembers his words clearly.
So after they marry, she keeps to herself, never asking where he goes and never hoping their marriage might become something more.
Until one day...
The night she falls ill with a high fever, the usually aloof man personally drives her to the hospital at three in the morning.
When her colleagues make things difficult for her, he defends her openly in the conference room for the first time:
"Not just anyone gets to bully Mrs. Gu."
Later, she happens to see an old photograph he has treasured for years.
The girl in the picture isn't her.
At last, Lin Wanqing understands.
She was only a stand-in from beginning to end.
She takes the initiative and asks to end their agreement.
But on the day of their divorce, Gu Chenzhou, usually so calm and restrained, loses control for the first time.
The man grips her wrist, eyes red:
"The agreement can end."
"But you can't leave me."
