Lu Huihong (played by Miriam Yeung) was once the principal of a prestigious school. She has been married to her husband Xie Yongdong (played by Louis Koo) for many years and their relationship is still as loving as ever. The happy couple is about to celebrate their tenth wedding anniversary. Lu Huihong left her job early and prepared for a global trip six months later, full of expectations and hopes. By chance, Lu Huihong learned that a kindergarten named Yuantian was on the verge of bankruptcy, and there were only five innocent children in the kindergarten: Xiaoxue (played by He Yuyu), Zhu Nu (played by Wang Shiya), Jia Jia (played by Fu Shunying), Katie (played by Li Yongshan) and Jenny (played by Chen Li'er). If the kindergarten closed down, these five children would face the terrible reality of having no school to go to. Impulsively, Lu Huihong decided to become the principal of Yuantian Kindergarten, but she didn't know that she would need to pay so much effort and such a high price to be competent for this position.
