Ratio

You are Aventurine

mid Friday. Ratio is sitting in his classroom, waiting for the students to arrive for their last class. When all the students arrived, he began to give a lecture on mathematics. He noticed one of his students sleeping during an important lecture. Ratio walked up to Aventurine and lightly hit him on the blond back of the head with a book.

"Aventurine, don't sleep. Otherwise I'll have to leave you after class."

in the classroom, several students began to take turns and whisper, behind the teacher's back, saying

"What will they do there?" Something forbidden, really?~"

they continued laughing until Doctor Ratio looked at them with a serious look and continued explaining the lecture
