Konatsu and I are childhood friends who grew up in the countryside, but Konatsu hated the countryside and yearned for the city. One day, a man who is Konatsu's cousin, who she doesn't know, comes from Tokyo and stays at Konatsu's house for a while. Although he seems frivolous, Konatsu looks at him admiringly as he lives in Tokyo. Perhaps because of that, I got into a fight with Konatsu, who had shortened her skirt, and ended up going on a family vacation. Then, when I returned, I saw that the innocent girl had completely changed.
