An unexpected trip for two with a female friend! Will they be able to go home without doing anything?
Our protagonist, Bota, and his girlfriend, Anoko, had planned a hot spring trip with their friends, the couple Tomohito and Aoi.
However, due to an unexpected problem, Anoko and Tomohito are unable to join...
Although neither Bota nor Aoi is partnered, they change their mind about a hot spring trip with friends and arrive at their destination, Kukago Onsen.

A hot spring trip with a female friend...I have a girlfriend, and she has a boyfriend.
Of course, there's no way I'd make a move. It was supposed to be just a two-day, one-night trip...or so they thought.
Exposed to the heat of Kukago Onsen, they find themselves doing things they wouldn't normally do.
What will happen to this hot spring trip...?

This is a simulation game where you can enjoy a two-day, one-night hot spring trip.
Spend the morning enjoying the hot spring town, check into a ryokan in the afternoon, and spend the rest of the day doing whatever you want with Aoi...That's the kind of game it is.
Since you only have 24 hours to play, it's impossible to complete all events in a single playthrough.
Multiple playthroughs are recommended.
(Each playthrough takes approximately 30-40 minutes.)

The main heroine is Aoi, while the supporting heroines are mother and daughter, Yuri and Kako.
While the story primarily revolves around enjoying life with Aoi, you can also enjoy events with Yuri and Kako.
