It looks like a nerd, Norio, had no friends and was having a lonely day.
One day, one of the electives was divided into classes.

Although Norio thought he had nothing to do with him, there came an encounter that changed his life.
“You’re next door from today. Nice to meet you.”

The girl who spoke to me next door was Ehime Shinomiya.

Norio will give her a favor and invite her to invite her to play.
In such a case, Ehime makes a man a real man …… It is discovered that it is a child who does so-called brushing down.

Norio will connect Ehime with what will become a “First-in-law contract” ……!?
