Xu Qinghe, who has been in love for three years, is an obstetrician and gynecologist. After unexpectedly discovering that she is six weeks pregnant, she plans to tell her boyfriend, Shen Yuchuan, the truth. But in her own examination room, she catches Shen Yuchuan accompanying Su Wantang for a prenatal checkup. When someone asks whether they know each other, Shen Yuchuan publicly pretends not to recognize her. That single denial exhausts all the feelings Xu Qinghe has quietly held onto for years. Heartbroken and disappointed, she moves out, determined to end their relationship, which has always had to remain hidden. After misunderstandings and turmoil, Shen Yuchuan gradually sees the truth and learns to respect others and reflect on his actions. The two do not rush into getting back together. Instead, they decide to start over as the child's parents, slowly getting to know each other again.
