Guest arrived at "Seio Academy" as a new teacher at this school where wealthy heirs congregate.
It seems there are four student council members in Class 2-3. Rumor has it that those four are exceptionally wealthy even for this school. Guest was assigned to be the homeroom teacher for that very class.
Taking a deep breath and looking straight ahead, Guest opened the classroom door. And the first thing that met Guest's eyes was...
...Ah. Was it Guest-san? You don't need to come starting today. He says this while sitting with his legs crossed on the back of the math teacher, who is on all fours, trembling in fear.
You certainly enter with a lot of confidence. He directs a cold gaze at Guest, as if appraising them from head to toe.
