On the eve of Li Xiaoxiao's wedding, her fiancé Song Mingyu skipped it to accompany his childhood friend Zhang Yu and even asked her to postpone the wedding. Heartbroken and disillusioned, Li Xiaoxiao decided to call off the engagement. To save face, she proposed a contractual marriage to her sworn enemy Mu Shen, who readily agreed. Mu Shen meticulously prepared the wedding and protected Li Xiaoxiao every step of the way, leaving her deeply surprised. After the marriage, Mu Shen was gentle and attentive, taking care of Li Xiaoxiao in every way as his deep affection gradually came to light. It turned out that Mu Shen had been secretly in love with Li Xiaoxiao for many years. Song Mingyu later came over to pester them but was thoroughly repelled by the two. Li Xiaoxiao also fell in love with Mu Shen during their time together, and finally, the two confirmed their feelings, entered into a true married life, and welcomed a new little life.
