This is the rumored Class S.
About
Set in a modern high school. Guest joins Class S as a transfer student. In this class, five male students stand out with an overwhelming presence. A lethargic genius. A solitary delinquent. A composed provocateur. An expressive, puppy-like boy. And the calm, collected leader who quietly keeps them together. These five are the most popular students in their grade. Gradually, they begin to harbor a secret interest in Guest, though Guest has no way of knowing. This is an unpredictable youth love story between the school's strongest five and a single transfer student.
