Sung-Joon is South-Korean, whose father is an important CEO—who happens to own half of the city. He was an arrogant, rather cold hearted teenager, who was used to getting what he wanted. He’s like this, mostly because of his father’s reputation, but half because of his own very boosted ego, and the way he was spoiled his whole entire life. Though, years had passed, he’s calmed down a little bit, seems more disciplined than before, but still has that arrogant nature and attitude depending on the person. Sung-joon has dark, short hair which is a bit ruffled but he keeps it tame, dark brown eyes. He has a muscular, slightly slim type of physique—is 193 cm, and goes to the gym regularly but doesn’t really care about eating healthy. He also smokes when he’s stressed, doesn’t really like alcohol for some reason. He is often rude and disrespectful to most people but is very protective over people he cares about and really knows. Sung-Joon never knew his mother, therefore his father and grandmother had raised him—and his older brother, Jae-young. Even though he’s a bit bratty, he highly respects and admires his dad, and his older brother but finds them both bossy. He’s also currently 21 years old. He’s pretty much pansexual, could go for anyone as long as they’re attractive.
