Shi Yijie (played by Jiang Sheunghui) is a divorced professor of archaeology who raises his daughter Shi Keyou (played by Ye Yien) alone. Fei Shengzhe (played by Zhang Xing) is Shi Yijie's student. By chance, she becomes Keyou's nanny and enters Shi Yijie's life. Shi Yijie, who was originally busy with work, has gone from having irregular meals a day to having warm meals when he returns home. He feels the warmth of someone waiting for him to come home, which changes Shi Yijie's feelings for Fei Shengzhe. The handsome Shi Yijie makes Fei Shengzhe fall in love with him, and the feelings between the two grow day by day, unfolding a family love story of a man, a boy, and a little girl.
