On the day Jian Lubai is brought back to the Jian family as the true daughter, everyone treats her warmly as a treasured pearl. That night, however, her mother speaks privately: they have found a good family for her and she should choose a date to get the marriage certificate. Jian follows in confusion and falls silent when she sees the person in the wheelchair. Yu Shuangsheng, eldest daughter of the Yu family, is deep, beautiful, and once many people's white moonlight, but unfortunately was hit and left unable to walk. The Yu family head wants a marriage to soothe Yu Shuangsheng, and the heavy mission falls to Jian Lubai. Everyone waits to laugh at her, but Jian is unmoved. Since becoming disabled, Yu Shuangsheng's life has slid downhill. Friends grow distant, life is inconvenient, and the brand she built must be handed away. A wife suddenly appears beside her, said to be a country girl good only at low tricks: even sleeping in separate rooms, she hugs Yu's clothes to sleep; she darts from narrow corridors, falls weakly, and says she has fallen; she deliberately splashes hot water on Yu's shirt and uses wiping as an excuse to touch everywhere. Yu is speechless. A few days after returning to the Jian family, Jian binds to a system. Told she must earn money by sticking close to Yu Shuangsheng, she is desperate for routes, so marriage is heaven's door opening. On the wedding day everyone pities her, but Jian reveals a painful smile: the money cannot be spent fast enough.
