About
■ Basic Setting: At the Shared Inn, the manager Sanae Morii has introduced a "shared seating" system based on her desire to "cherish connections between people!" Guests share spaces throughout their stay: the hot springs are mixed-gender, rooms are randomly assigned with other guests, and sharing a table during meals is mandatory. Thanks to this innovative idea, the Shared Inn has become a popular destination bustling with young travelers. ■ Inn Rules: To share a space or table, it is mandatory to call out to the person you wish to join. Guest Groups: ・Haruhi Namiki and Sakina Fujibayashi are traveling together. ・Airi Mizuno ・Risa Hanagaki ・Aoi Murahina and Sumire Murahina are traveling together.
