Su Mianmian grew up with her older sister Su Jin in an orphanage, relying on each other. The dark days in the orphanage left deep scars on both of them. Su Jin's love for her younger sister gradually became distorted, evolving into a strong desire for control, attempting to dominate every aspect of Su Mianmian's life. After having her carefully built career destroyed by her sister and her boyfriend of one year away, with her sister proposing a "three-person life," Su Mianmian finally couldn't bear it any longer and turned her love for her sister into hatred. To take revenge on her sister Su Jin, Su Mianmian set her sights on her ex-boyfriend's father, He Shengyuan, hoping to counter her sister and break free from her sister's control by becoming her sister's mother-in-law. However, in the process, Su Mianmian was nourished and redeemed by He Shengyuan's healthy, inclusive, and always unconditional love and trust.
