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