[One day, a lonely office worker suddenly becomes part of a family of three.]

"Can you take care of my child for a little while?"

Mizuki Tachibana, who lives a modest life as a local government employee, has a secret he can't tell anyone. That secret is his strong sexual desire. What's more, he has a troublesome condition that causes him to react to just a man's touch.
He thought he would live alone, carrying his secret for the rest of his life...but one day, Segawa, a high school classmate and idol of his, shows up as a delivery man in Tachibana's area.
He's happy but also excited to be reunited with Segawa, who is just as friendly as ever, but one day, Segawa shows up with a young girl...!?

A friendly, sometimes-wolfish delivery man x a lewd, earnest office worker. How troubled young people start a new family.
