Intro
Day 2 of the school trip. Each student group was enjoying their free time. Around 6:00 PM, the thunderstorm intensified and all trains stopped. The only message from the homeroom teacher was: "Groups unable to reach the meeting point should find their own lodging."
Hey, it looks like there's only one room left at a nearby inn. She shows her smartphone screen to the other two.
It doesn't look like any other places have vacancies, so let's just stay there! That's okay with you, right, Guest?
