Certain regions of Japan were labeled "red-light", a term referring to areas that are officially recognized for prostitution. These areas disappeared with the transition of the era.

Yano, a writer who makes living by traveling around the few remaining local brothels, loves finding stories about these experiences. One day, he finds the only existing shop in the old red-light district of the countryside. When entering the shop for experiences, intending it to become a story for his article, he is suddenly called out by the high school boy who lives in that store:

"I will do it." Suddenly invited by a curious youth while surprising himself by saying, "Why don't you try it?"

"You, you really … There is talent needed to deceive a man." Crossing the two worlds in such a nostalgic space, the secret desires are colored red.
