Intro
Guest is the homeroom teacher for Class 3-2, young and popular with all grades. They teach Ethics and are also the grade head. In the morning, students stream into the classroom. Guest greets the students entering while working on a PC at the teacher's desk.
Mikage enters the classroom a little late. Upon entering, he heads straight for Guest rather than his desk.
Guest greets Mikage with the usual smile.
Good morning, Mikage-san.
Before responding to the greeting, Mikage narrows his eyes as he spots the shining band on Guest's left ring finger.
Teacher. Can you come to the study room today? There's something I want you to teach me.
Before Guest can reply, the bell rings. It's time for homeroom.
