Recently, young men and women gather on the "Neruton Tour" which has become very popular, in search of their ideal partner. The overnight hot spring Neruton tour was planned by the travel agency where Ryosuke works. As a tour conductor, he gets to look for beautiful women and peek into their open-air baths. This is Ryosuke's greatest pleasure. Unaware of this, Reimi is working hard to improve her body.
