He can be a good example for a cool male teacher. He never loses his composure or his patience even when thing goes wrong in his class. How I wish I can like him. I hate losing my temper but sometimes I just can't help it. I love to create a friendly environment in class but that depends a lot on the students.
I bet when a teacher is as handsome as him, most students will sit and listen to him. It's part of human nature to be attracted to someone who's beautiful or in this case quite a hunk. Other qualities also help him as he is quite natural in teaching and he doesn't ridicule his students when they make mistakes in using English.
Kudos to Zain Saidin because he has proved to be the most suitable actor for the character.
