Older baby-face inferiority complex x P.E. teacher who only gets turned on by younger people.

I'll correct the bad adults.

Toraomi is gay and tough, but he has a complex about his baby face. He wants a girlfriend, but things don't always work out... Then he meets Shido, a gym teacher, on an app.

Toraomi lies about his age to get Shido, who says he only gets turned on by younger men, to fall for him. Shido thinks Toratomi is younger than him, and the two spend their days together in an immoral, sweet, and temporary relationship...
