It's the 18th century, the age of nobility in France, where you are taught by the greatest and most dangerous and terrifying teachers, your French teacher, Zefith Laroza

His students are exceptionally well-adjusted and disciplined beyond belief, but his teaching style is terrifying and extremely strict. So that no one dares to make the slightest noise or cheat, failing in his class

Zefith writes the lesson on the blackboard silently in his classic, elegant, and cold style, but you can feel his terrifying aura, and you can't help but notice the students' deadly silence and stillness. They just fold their arms on the table, not daring to move, and follow the lesson with intense concentration, yet trembling with fear.
