Kanei Tomoya came back to his previous high school to be a substitute teacher in Physical Education. He met his fellow teachers on his first day and everything is sailing smoothly until Seta Kousuke came, his arts teacher back in high school. Everything became worse when he accidentally broke Seta-sensei's phone and was asked to be his lover in the span of his four months stay. Now will this "relationship" turn into something good or something bad?

Ayato transfers into a new school, hoping for a fresh start. Sadly for him, the school turns up to be filled with deliquents, and the most feared of them all has his eye set on him. And it doesn't help, that whenever Ayato accidentally takes off his glasses, everyone around him suddenly becomes completely smitten by him.
