Lin Wan served as a full-time housewife for ten years, only to be swept out the door by her successful former husband. Driven to desperation, she applied to be a live-in nanny to care for Lele, the taciturn and autistic son of the power holder Fu Chen. With her gentleness, she slowly healed the child, finding a foothold in the Fu household. Her former husband repeatedly came to her doorstep to humiliate and harass her, but Fu Chen stepped forward every time to protect her, proposing a nominal marriage to shield her from the chaos. Accompanying each other day and night, the two fell in love; Lin Wan walked out of the pain of her marriage, picked up her studies and career once more, let go of the unbearable past, and ultimately lived in faithful companionship with Fu Chen and Lele, possessing a stable and warm little home.
