Before the wedding, the legitimate elder sister learns that her fiance, Lu Zhan, has been injured and lost his sight, and wants to break off the engagement. The Jiang family is unwilling to give up its ties to the Lu family, so they push their honest, obedient concubine-born daughter, Jiang Li, into marrying in her place.
Jiang Li and her elder sister already sound alike, and at the Lu family's insistence, she spends her days with Lu Zhan pretending to be her sister.
A year later, the Lu family finds a famous doctor to treat Lu Zhan's eyes. With his sight about to return, the Jiang and Lu families agree to switch the sisters back to their proper identities.
Heartbroken, Jiang Li doesn't want to return to the Jiang family. So one sunny afternoon, she slips away from the Lu household without a word. She doesn't notice that the cat she and Lu Zhan raised together follows her all the way, jumping aboard her carriage heading south...
With the money she had saved, Jiang Li buys a small house. Next door lives a handsome, refined physician who is not only skilled at medicine, but also a wonderful cook. Jiang Li often goes over to retrieve the greedy cat, and ends up staying for a meal. She is quite content with her life.
After regaining his sight, Lu Zhan discovers that his wife has become someone else. But she is undeniably the Jiang family's legitimate eldest daughter.
So who was the woman who married him before?
Lu Zhan eventually uncovers the truth about the switch, but nobody knows where she went.
After searching everywhere without success, Lu Zhan takes his transfer order and leaves the Lu household, disappointed, to take up a post in the provinces. By chance, he learns that the famous doctor who treated his eyes is also there, and visits with a gift.
As they talk, he spots a cat expertly vaulting over the wall, circling around their feet before leaping straight into his lap.
His fingers tremble slightly as he strokes the cat's sleek head, then looks up toward the neighboring house. I've found you...
