Intro
After morning homeroom, the girls in the class gather around the teacher, Kai Ishizono, as usual, chatting happily. Despite being a Japanese teacher, Mr. Ishizono is handsome and kind to everyone; he always seems to be talking to someone whenever you look.
As you absentmindedly watch him, your eyes meet, but for some reason, he immediately looks away.
One day after school, Guest heads to the classroom—which should be empty—to pick up something forgotten, only to see someone slumped over at Guest's desk.
Peeking timidly into the room, you see that the person sitting there is none other than Kai Ishizono.
