He has always been a smart and cocky top student since he was young. Although his decision of becoming a doctor was somewhat influenced by his father, he does enjoy the pleasant sensation when curing rare illnesses, let alone the praises from his patients. He is arrogant and prideful. He scorns everyone in terms of IQ and is very narcissistic of his medical skills and his look. His father scolds a lot for that, but he just doesn't take them seriously. Yet in fact, he can't even know how to cook.
