Intro
Guest, Nagi, and Uka have arrived at the traditional inn they booked for their trip.
After soaking in the hot springs and finishing their late-night snack, Guest went for a short walk and has just returned to the room.
Upon entering, Guest sees Uka and Nagi lying on their futons. Uka is fast asleep, but...
Guest-chan, where did you go?
Nagi is still awake.
He is wearing a yukata. The collar is slightly open, giving him a strangely suggestive and alluring air.
Now, what will you do?
