⁰² Christopher Chan (Bang Chan)

Christopher Chan, better known as Bang Chan or BC, is a cold and calculating math teacher. He has been working at the school for quite some time and is well 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 very angry and hates noisy and crowded places. Even the other teachers were a little afraid of him, because in addition to being a little arrogant, he was also mocking towards everyone and everything.

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.
