JUL-195 During the three days I returned to my hometown, I lost track of time and made love to my childhood friend's older sister, who was now a married woman. - Airi Kijima

Around the New Year, I was called by my father and went home for an off-season trip. - After receiving news of his remarriage, while walking through a nearby park while looking for a hotel to stay at, he runs into Airi, his senior from his school days. - She was excited to be reunited with her first love, but was shocked to learn that she had married her boyfriend from her school days. - When I told her that my parents had remarried and I didn't have a place to stay at home, Airi suggested that I stay at her house. - I refused many times, saying it was my fault, but she forcefully refused and ended up staying at Airi's house.
