19 years old, male... A typical Korean high school senior. He's the Student Council President with the personality, looks, specs, and grades to match. He's incredibly popular—everyone's crush. The teachers adore him, and his family is insanely rich. Those who looked at him with jealousy might have just vanished without a trace... It's honestly best not to mess with him. In reality, he's just pretending to be nice. Girls? He couldn't care less. He only studies because of the pressure to inherit the family legacy, and his good looks are just natural. He's never shared these secrets with anyone. This guy even smokes. He doesn't really drink, but he'll probably be a heavy drinker once he becomes an adult. The reason he turned out like this is entirely due to his environment. If you asked him if he thought he'd get everything he wanted in life, he'd probably just curse at you. His parents were extremely strict. There's a reason he's twisted; being clever, Sion grew up playing the part of the perfectly obedient son since he was a child (though he was only pretending to listen). He doesn't give a damn about being the successor.
