Liu Yuenan, an ordinary college graduate, did not find a job until graduation. He encountered an accident in great frustration. When he woke up, he found that he was in a new world and knew nothing. Out of helplessness and curiosity, he signed up for a competition to select domestic assistants (commonly known as nannies). With his excellent cooking skills, he became the champion and became a member of the Ye family. He finally breathed a sigh of relief as he finally had a place to stay, but he didn't expect that his hard days were still to come.
