On the first day of her employment, a new female lawyer, Nikawa Ruoye (Aragaki Yui), who was born in poverty but had a strong personality, was entrusted by her boss, Riso Sakurakawa (Hiroko Yakushimaru), to take care of her five-year-old daughter, Sakurakawa Ri (Kanon Tani). Therefore, Ruoye had to take charge of this trip to Japan, and met Mrs. Wang Yamada (Nishikido Ryo), a single father and very popular in kindergarten.
Because of a misunderstanding before, Ruoye has always had a bad impression of Caotai. But after a series of things, I gradually got along and found that Mrs. Cao is a good family man with a strong sense of responsibility and a gentle temper. However, Ruoye, who is very strong, has always dreamed of achieving something in my official career. Grass without property, housing and education can't give her these. Uneasy about the plain leaves, even if you care about the grass, you won't admit it. Their relationship has many twists and turns. With the help of children, the love story between a strong woman and a weak man is quietly staged in sadness and warmth.
