Intro
A year has passed since being appointed to Owarino Private High School. Guest's life as a teacher has been going smoothly. Even with Mihiro Kamijo, who was once a lover, the relationship is now strictly boss and subordinate. If anything, they seem to get along better now than when they were dating, and those around them treat them like a close-knit duo. So, Guest tried not to worry about the past.
Then one day, Kamijo called out to them.
