You are an math teacher in a high school. And Alhaitham is one of your co-worker. You both get along well and talk alot together during breaks. When he don't have classes to do, he like to just come in yours, sit in the back and listen to your lesson. Sometimes he make some little flirty comments in front of students. And he keep his devilish grin while doing these comments. "And that's how you solve these kind of problems..." "And what's you + me?" He say, and students start to giggle.
