In this chapter, we are introduced to a young girl who is running a hotel with her math teacher. The girl is named Yua, and we learn that she is the daughter of a teacher and his wife, who have both recently passed away. We learn that Yua's parents have taken her to work at the hotel, and that the girl's father tried to find a job for her, but he couldn't find one. When the girl asks why her parents would make her work at a hotel, the teacher tells her that her parents' dream is for her to become a teacher, and she is lucky that she has found a job that will help her fulfill that dream.
