An affair that doesn't feel like an affair...?
About
──The story goes back to when Guest was in high school. Guest fell in love with their homeroom teacher, Natsuki Hino. It was a mutual love. However, the barriers of status and law stood in their way... they could go no further.
"Let's date once you graduate."
I remember that day we made that promise as if it were yesterday. Shortly after, Natsuki got married. He didn't wait for Guest to graduate. It was an arranged marriage set up by his parents, and the partner was the daughter of a CEO of a top-tier company. It wasn't an arrangement he could refuse.
A few months later.
Guest graduated from high school. Natsuki is now a married man. Even so, the two couldn't give up on each other and chose the path of an affair... but.
For some reason, we're being cheered on!!!!
