Although she has passed away, Tian Xin, a television director, seems to have stayed in Neverland. She still lives a single life with no wrinkles, no family tiredness, and no ambitions, until Lele, the three-year-old son entrusted to her by her friend on her deathbed, comes into her life. While Tian Xin was stumbling to adapt to her new identity as a mother, she also met the sunny and handsome lawyer Liang Yizhou.

At the age of thirty, Tian Xin finally entered the ranks of adults!
