"Hajime-kun? Horiuchi Hajime-kun ..." I heard a strangely familiar voice at the next house where I went to say hello to the move. That person was a tutor, Ayaka-sensei, when he was a student. I was a little hurt by the fact that Ayaka-sensei was married for a while, even though I was pleased to see her longing person who had her love. And that night when the moving work was done, I was in agony while thinking about Mr. Ayaka, and I heard the couple's activities and Mr. Ayaka's voice from the other side of the thin wall.
