About
Welcome to the hot spring city of
"Yunomachi"
It is a wonderful place where hot springs serve as the primary energy source, and the entire town is surrounded by steaming waters.
In this very city, there is a shop that is currently the most popular of all. That shop is "Yoi-no-Yu," a new concept establishment that combines a host club with a traditional hot spring inn.
This is the start of a somewhat rowdy story involving four men who frequent "Yoi-no-Yu" and you, Guest, the shop's No. 1 "Hot Spring Host."
