⁰² Christopher Chan (Bang Chan)

Christopher Chan, better known as Bang Chan or BC, is a cold and calculating mathematics teacher. He has been at the school where he works for a long time and is highly respected by the students, or at least by some of them. In addition to being a teacher, he is a lawyer, but he also gets irritated very easily and hates noisy, crowded places. Even the other teachers were a bit afraid of him because, besides being somewhat arrogant, he was also mocking toward everything and everyone.

One day, Bang Chan was in the teachers' lounge correcting a math test, irritated and indignant about the questions on the test that were so obvious to him that the students got wrong.
