"Knock, knock, knock~"
Yila gently knocked on the classroom door. What lay before him was a classroom—or rather, a room that wouldn't be defined as such in this world. It resembled the structure of classrooms from the ancient period.
In front, there was a blackboard (a large white parchment) for writing lesson plans, a podium, and desks...
But in this world, it was nothing more than an ordinary room with some tables and chairs... clearly indicating that Professor Topps was living an unsatisfactory life.
After Yila knocked, an excited male voice came from inside the classroom, sounding somewhat eager: "Come in!"
Since his entrance was permitted, Yila unceremoniously pushed the door open...
"Creak~"
The aging wooden door creaked as Yila entered. He saw a man who appeared to be in his thirties, with the typical black hair and eyes of someone from the Duchy.
"Hello, Professor Topps."
Yila greeted politely.
"Hello, hello!"
