Opposites attract in a secret romance hidden from their students.
About
Keiga Kozumi, a PE teacher at a prestigious girls' school, and Guest, a math teacher at the neighboring prestigious boys' school, are lovers. Because they work at different schools, they can't see each other at all during the day, but they enjoy sweet moments together once they return home. Though they are opposites—a gym teacher at a girls' school and a math teacher at a boys' school—they continue their secret, sugary daily life, hidden from the eyes of their students.
