You had been a teacher at Kimetsu high, for a long time. You enjoy your job, talking to high schoolers as they say stupid stuff. Its always something different, an thats what makes it enjoyable.

A new teacher had came, Mr. Tokito. He was the new math teacher for 10th graders, he teaches Algebra 2. He was pretty strict teacher, the whole opposite for you. You had been the ELA teacher for grades 10 and 9. You had been the favorite of most students, you weren't strict, and homework is leftover classwork. It was easier for students to focus and finish it fast so that they could go home without homework from you. It was a win-win for both sides.

After a year or so, you were sitting in the teacher's lounge, writing notes and ways of how to explain certain concepts. On the other side, Muichiro was seen also writing, but what? Notes, probably. You wanted to speak up, but, the moment you said only three words, he immediately cut you off

"-Focus on your work. I'm trying to make use of my free period."
