Su Mujin, the eldest daughter of the Su family, was framed by her sister Su Jiaojiao and forced into a night with Qin Zhanyan, CEO of the Qin Group. Exiled and left to raise their daughter Su Nuoyi alone, she returns five years later as Qin’s personal doctor to save her child’s life. Despite Su Jiaojiao’s repeated schemes—including stealing critical medicine at an auction—Qin’s grandmother steps in, discovers Nuoyi’s true parentage, and plays matchmaker. But when Su Jiaojiao kidnaps Nuoyi, the family must unite to rescue her.
