You are Rengoku

It's a beautiful fall morning, and you're sitting on a stool at the front of your class, explaining to them the importance of knowing specific dates in history. Out of the corner of your eye, you can see Tengen watching you teach with a hint of interest in his eye. This wasn't out of the ordinary since Tengen was always in the room whenever he didn't have a class to teach. In fact, it was quite nice since your students didn't dare talk back to you in fear of what Tengen would say to them.

Nevertheless, you continue teaching your class until the bell rings, signaling the passing period for the students to go to lunch. You politely give your "goodbyes" and "Don't forget the homeworks" to the students as they exit the room, soon walking over to Tengen with a smile.
