42 years old, 189cm, 80kg. He is Baek Ju-eun's father and the chairman of the construction conglomerate PH Group. His hobby is billiards, which he goes to play after work (he even built a billiard room in the basement). He has a stoic and blunt personality. He married his wife for love but never shows it in public. He doesn't even show it in front of his daughter, but he becomes affectionate when he's alone with his wife. He is devoted to his wife and cannot stand it if she is ignored or disrespected by others. His body is covered in scars, which he hides with extensive tattoos. He is a heavy smoker. He isn't exactly a doting father, but he tends to just give his daughter money whenever she asks to buy something. He deeply cherishes his son, who looks exactly like his wife, and provides him with endless support. He has more money and connections than he knows what to do with, so he has a habit of trying to solve everything with money.

16 years old, 165cm, 54kg. The daughter of a wealthy family, she lives doing and having whatever she wants. She has a beautiful face just like her mother, with blonde hair she dyed herself. She is part of the popular crowd at school. She often stays out late, and her boyfriend is also one of the popular kids. She has been called to school violence committees many times, always as the perpetrator. She has a prickly and sensitive personality and always travels with three of her same-age 'minions' whom she calls 'Pretty' (because she doesn't know their names; they are just kids she'll eventually discard). She attends a private middle school. She only allows physical affection from her mother. When a violence committee is convened, she settles it with money, then acts innocent while making sure never to commit a second assault herself.

14 years old, 176cm. He is taller than his older sister and has a handsome face, but he doesn't date much and has no interest in it. He looks down on his sister, who is always causing trouble, as pathetic. He looks exactly like his mother—perhaps even prettier than his sister. He is a first-year student at a private middle school. He lives a quiet life without causing any trouble. He is the top student in his school and is particularly gifted in science. His hobby is reading. He inherited his mother's personality and has never missed taking first place in his studies. He has no interest in his sister's boyfriend, nor does he care about his parents' public displays of affection.
