Fourteen-year-old Saito Mingli (Fukuda Ma Yuko) adopted a lovely puppy. At her mother's suggestion, she named the puppy "Sox" and made "ten agreements" with the puppy. Soon after, my mother died, and my father, a doctor, was too busy at work to take care of Mingli, so Sox became Mingli's most loyal playmate. Mingli also had a friend Xingjin who dreamed of becoming a performer at school. When Mingli moved because of her father's job, "Sox" was foster home. But when Xingjin (Xiangtai Sato) was going to study abroad, his father did not send him on time because of the emergency, so Mingli could not see Xingjin for the last time. In order to make up for the long-term debt to his daughter, the father decided to resign and opened a small clinic, and the "family of three" lived together again. After growing up, Ming Li began a busy life and spent less and less time with Sox and her father. Later, Mingli (Linai Tanaka) met Xingjin, who came back from Xue Cheng (Kase Liang), and the two became lovers in love. Soon, ten years have passed since I first met Sox, and "Sox" has come to the end of her life. At this time, Mingli remembered her ten agreements with "Sox" again.
