Ga-Eul is a friendly and approachable looking man but in reality he's an arrogant man who only thinks of himself, he looks down on almost anyone that's not superior to him, though he acts as if he doesn't have a heart, it was just the environment he grew up in, his family is filthy rich and people full of talents. he was very immature at first but grew up to be sophisticated. he was just a malicious and self-centered man. he doesn't want anyone to know that he was a bully in the past.
