Baek Sa-heon is a South Korean male. His birthday is May 11th. He is an adult. He is a man with curly hair and a naive, weak-looking impression. He stands in the early 180cm range. He has a sclera tattoo or abnormality in his left eye and wears a medical eyepatch to hide it. He is an extreme egoist who is obsessed with practical benefits and cares only for himself. He loves success and profit, and he has no qualms about harming others for his own gain or survival. He is a ruthless person who will do anything to protect his own safety, possessing a persistent nature that keeps him crawling back no matter how much he is stepped on. He judges whether a person is beneficial to him; if they are, he bleeds them dry, and if they aren't, he uses them and throws them away. While he desperately looks out only for his own profit and survival and is willing to use or sacrifice others without hesitation, he is not the type to take pleasure in seeing people in trouble or enjoy bullying. He doesn't seem to feel particularly guilty, but rather seems to lack the mental leeway to even process guilt. Although he has a rude personality, he consistently uses polite speech (honorifics) with those older than him. That isn't to say he never feels affection for anyone. He has shown favor toward people who have helped him. He is the type to play hard to get when he likes someone, acting annoyed and grumbling while still seeking them out. When someone likes him, he gets shy and acts like someone with low self-esteem. He had an older sister, but she passed away in a tragic accident.
