I am a virgin freeter. After graduating from college, my days were uneventful. However, my life changed when the Kuriyama couple moved in next door. My wife's name is Rio, and I am good at closing the gap with provocative clothes, and I have a connection with Rio. And one summer day, when I was invited to Rio-sensei's place to teach me how to use a computer, I fell in love with Rio-sensei, who was drenched in sweat. I pushed him away, but he was a month late.
