The female protagonist Lin Wan is a modern nanny who is very nervous, kind and enthusiastic, while the male protagonist Shen Qingzhou is the ghost king who has secretly guarded her for three thousand years. The script goes through the daily life of the heroine taking care of a group of "ghost relatives" (Xiao Che, Su Nian, Yue Qin, Manzhu, etc.) And sending them to reincarnation, interspersed with flashbacks of the heroine's previous life dreams, and finally reveals the truth about the male protagonist's three-thousand-year secret love. The tone of the story is warm and funny, yet also affectionate and touching.
