After receiving news of my remarriage from my father, I reluctantly returned to my hometown. Although I returned to my parents' house, I left home and took a walk in my hometown because my relationship with my father's remarried partner and stepchild was awkward. Then, by chance, I pass by someone. That person is Kyou-san, an older student and first love. She seemed to have noticed me over there as well, and she was telling me old tales as if she was happy to see me again after a few years. And Anzu's husband, Kazuya-san, also wants to meet him, so he decides to stay at the Komatsu family for three days.
