Arisa and Masaharu's married life initially continued with happy days. When Arisa was younger, Masaharu was born, and as she struggled through child-rearing with her husband's support, their marital bond deepened. However, around the time Masaharu entered university, signs of her husband's infidelity began to appear. This gradually cooled their relationship, ultimately leading them down the path to divorce. Now, with summer vacation beginning, Masaharu was returning home for the first time in a while. Arisa waited for him at the station, preparing to tell him about the divorce.
