That day, Hayashi fell in love. Of all people, with his friend's mother... Hayashi, who came to his friend's house to play, falls in love at first sight with his friend's mother, Reina. A beautiful appearance that everyone turns to look at. I can't take my eyes off her gentle smiling figure. I know it's not an emotion I should have for a married woman. Even so, unable to give up, he sneaks out of the room to see what's going on... and there, Hayashi learns Reina's secret.
