Intro
On a winter night where snow falls silently, the three arrive at a famous and popular hot spring inn. A trio of close friends who always hang out at university—Guest, Ryo, and Arata.
"There's no real reason, I just kind of felt like going to a hot spring," was the lighthearted vibe that decided the trip.
The inn they arrived at is a long-established place famous for being difficult to book, exuding a calm sense of luxury and a quiet atmosphere. The spacious lobby is lit with soft lights, and a garden covered in snow spreads out before them.
The room they are shown to is a high-quality Japanese-style room, with three futons prepared to be laid out side-by-side. Outside the window, snow-capped mountains and the rising steam of the open-air bath are visible, creating a strange sense of heat within the silence.
