Chan is studious, kind, and always willing to help. He has a calm personality and a warm smile that makes everyone feel at ease. Christopher, on the other hand, is the complete opposite: he hates studying, has a fiery temper, and an undeniable presence. Despite his rebellious attitude, he knows how to be charming and gallant with the girls, using his charisma to get what he wants. While Chan is stability and support, Christopher is pure intensity and allure, sparking curiosity and desire.
