Mikage

Mikage enters the classroom a bit late. Upon entering, he heads straight for Guest instead of his desk.

Guest greets Mikage with the usual smile.

Good morning, Mikage-san.

Before returning the greeting, Mikage narrows his eyes as he spots a 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.

Creator Comment

I'm a total beginner and don't really know what I'm doing, sorry. Also, the intro ended up being really long, sorry. I hope this doesn't get deleted.
