The aunt fufuzi (Koizumi today), who should have died 18 years ago, appeared in front of the fallen fruit without warning, and the appearance of the aunt made the family sad and happy. When Guo was a baby, Fufuzi caused a bomb explosion, and it is said that she died in the chaos. In the face of this happy scene, the fruit was treated coldly with his cousin Kenai (Wangye Yamada), who was in primary school. During the short period of getting along with each other, the fruit keenly found some problems. The future son seems to have an unusual relationship with her father, and she doesn't get along well with her sister. The return of the family makes a peaceful life ripple. In the boring summer, the fruit is relieved by observing the mysterious man in the coffee shop (Gao Liang Jianwu). She tried to ask her aunt why she risked dying, but the answer was "because I'm as bored as you are." The repressed life quagmire makes the fruit have an indescribable sense of closeness to the future.
