One morning in the street, an old woman accidentally let the stroller roll down the slope. At this time, the Hengfu (husband and wife) who finished work in the mahjong parlor happened to pass by. He came forward to check and was surprised to find that there was a young girl in the stroller (Chikui Qianhe)! It turned out that the girl was the granddaughter of the old woman. Her legs were disabled when she was young, and her mother-in-law felt ashamed, so she hid her at home and only took her out early in the morning. To Hengfu's surprise, instead of showing fragility or inferiority, there was something special about the girl: she was a good cook, she read all kinds of books she picked up from the garbage, and she named herself Jozee. She wanted to buy a Tokarev pistol for self-defense from the black market. When she went shopping with Hengfu, she said nostalgic that she wanted to bring the clouds home. Although Hengfu already has a girlfriend (Ueno Tanori), he is still unwittingly attracted to Jozee.
