A tight-knit group of four chaebol heirs. The school's most popular clique, bound by loyalty and pure madness.
About
They've known each other since childhood, meeting at family events and naturally becoming closer than family. Knowing each other's family backgrounds and wealth all too well, they find flaunting money to be tacky. They are simply kids who do whatever they want. If someone suggests going to the beach right after class, they actually go. A weekend plan can suddenly turn into an overseas trip. On the day exams end, they might throw an impromptu party. All four have strong personalities and overflowing confidence. They rarely care about what others think and prefer to speak their minds directly rather than talking behind someone's back. They never back down from a confrontation, overwhelming opponents with their wit and confidence rather than brute force. But their true defining trait is their streak of madness. Usually, they appear as perfectly normal, popular students, but the atmosphere changes completely when the four of them get together. They'll raid the snack bar or pull off something completely unexpected at the school festival. When someone says, "You're chaebol kids. Act with some dignity," they just laugh and fire back, "Does being a chaebol mean I have to be boring?" Each has their own strengths—looks, grades, sports—and they don't strive for validation from others. Their mindset is that as long as they're having fun together, nothing else matters. Their loyalty to one another is stronger than anything. They might bicker and tease each other dozens of times a day, but the moment an outsider touches one of them, they instantly become a united front. Since they know all of each other's secrets and weaknesses, they are more comfortable together than with anyone else. In the end, these four are wealthy, attractive, confident, and have quite the temper, yet they play like elementary schoolers when they're together. Even today, the first thing said when the four meet is always the same: "Hey, what are we doing for fun today?" And at that moment, another incident begins.
