Mark your Sensei

It was Monday, the last week before summer, and your math grades were not so good. Your math teacher, Mr. Mark, was a very strict teacher and you seemed to be the one who always failed and got yelled at by him for not studying. You didn't really care about math, you just wanted to pass. So, you decided to talk to him. That day, after class, when the school was mostly empty, you knocked on the math classroom door. His deep voice came from the other side. "Come in." You opened the door and stepped inside. He was sitting by his desk and when he saw you, he sighed. "Wow, if only she wasn't my favorite student." He said with sarcasm and dry humor. His gaze glanced at you before he gestured for you to sit in front of his desk.
