On her wedding day, Ji Siheng, heir to the most prestigious medical family in the capital and a renowned young genius in cardiac surgery, is publicly humiliated when his fiancée switches grooms, leaving him in his wheelchair. "Whoever catches it will become the mistress of the Ji family!" The next second, the doors burst open, and a silly girl riding a pink alpaca crashes into the wedding. The wedding ring lands perfectly on the alpaca's horn. With a candied hawthorn skewer in her mouth, she points at the gloomy Ji Siheng and declares, "Husband, Niao Niao will marry you!" She pretends to be foolish and marries him, wanting neither his money nor his power, but only to redeem a ticket that can change her fate.
