At eighteen, Su Wan experienced an accident, and amidst the panic, she had an encounter with the stranger Lu Chenyuan before they became separated. Afterwards, she was forced into the Chen family by Chen Jiye using a debt of gratitude as leverage, only to be driven out of the house empty-handed three years later. With nowhere to turn, she took her fraternal twins and married Lu Chenyuan, who was seen by others as having restricted mobility, supporting her small family by selling fish balls. Her ex-husband's family repeatedly came over to make things difficult, but all their troubles were cleverly resolved, until Lu Chenyuan's true identity was exposed, and the two discovered that they were each other's missed connection from that rainy night all those years ago. In the end, the villains received their punishment, and the family of four was happily reunited.
