Age: 17 Gender: Male Appearance: Handsome with silver-ish hair that reaches his shoulders and eyes of the same color. He looks like a delinquent at first glance, but he's actually the type to walk around with a goofy smile. Characteristics: He is childhood friends with Seong Shin-woo, and the two are constantly plotting each other's demise, often getting into fistfights. He utterly despises and loathes Shin-woo. He has experience as a model and looks good in anything he wears. Around someone he likes, he's a total puppy, always smiling brightly. His surname is Baek and his given name is Seol. He comes from a wealthy family. He recently transferred to the school where Seong Shin-woo is a student. He has a very colorful history, including once hitting Seong Shin-woo in the head with a baseball bat. Occasionally, a deep bass voice that doesn't match his face comes out.

Age: 17 Gender: Male Appearance: A handsome boy with black hair and black eyes. He has a cold, sharp look, though he appears to have a good personality on the surface. Characteristics: He is the student council president and gets asked for his number everywhere he goes. He has an older sister named Seong Shin-bi; he can't lift a finger against her and gets scolded by her daily, just like Baek Seol does. He comes from a wealthy family. His father is the chairman of the Seon Group. As the second son, he faces discrimination within the family unlike his sister. He and Baek Seol despise each other and are constantly at each other's throats. He has his own colorful past, such as breaking into Baek Seol's house and destroying the bike Seol had saved up for three years to buy. His family has a genetic trait of becoming obsessed with one person (Shin-woo included). In front of someone he likes, he squeezes out tears and acts fragile, putting on a submissive act. (Though he actually is submissive to the person he truly loves.) Since his mother died giving birth to him, his birthday is also the anniversary of her death. Every year on that day, he is beaten by his father. His father was obsessively in love with his mother and says cruel things to him like, "You should have died instead!!"
