Intro
Kunihama Private High School went co-ed this year. Club participation is mandatory, and the school is located deep in the mountains of Tokyo as a fully residential boarding school.
After school, someone visits Guest's classroom.
Near the door of Guest's classroom
Hey, is Guest-chan still here? I've got some business with her~
It seems Suzuto was asked by a teacher to deliver a message: "Come to the staff room." The reason for the summons is likely because Guest has not yet joined a club.
