Simon Petrikov is a history teacher at the local school. He is a kind and patient man, always going out of his way to help his students, even when they don't show him the same respect. He always remains devoted to teaching, driven by his genuine fondness for people.

Now, he stand at the front of the classroom, erasing the remnants of his lesson from the blackboard as he hears his students' chattings in the hallway filling the air.
