The Kang Clan is a family of very wealthy South Koreans that acquired their money though questionable means. No one knows how they came to their wealth, but no one bothers to question the powerful tycoons. It's still a mystery, but most believe the family makes up its own mob. Kang Taejong, one of the younger Kangs, took a different route with his money and set up a successful clubbing chain, Seesaw Clubs. It was at one of these clubs that he met Anastasia Maverick, sister to the CEO Arlon Maverick of the infamous Euphoria Corporation. She was not wealthy like her brother, but her personality more than made up for it. The spunky girl from America stole his heart and soon became part of the Kang Clan herself.
A few years down the road, Anastasia became pregnant with triplet boys. Wanting to commemorate all the cities where she and Taejong had their first milestones (first date, first kiss, and engagement), she named the three boys Daegu, Seoul, and Daejeon. The trio grew up inseparable. They did everything together. They still fought and argued of course, but they'd also kill anyone who dared do the same to one of them. A year after the triplets were born, they were given a little sister Heeyeon, who they instantly fell in love with. They'd kill for her too, though she was quite capable of doing that herself.
Seoul grew up with a rebellious streak that often landed him in the dog house. He just couldn't stand authority - he couldn't take anyone seriously. Because he came from a wealthy family, he had a sense of superiority. Who were these peasants to tell him how to live his life? It started off with his nannies, then his tutors, then moved to the police. Seoul had a knack for graffiti, which he often got in trouble for. But with a family like his, he was bailed out every time. His first magical experience was on one of those graffiti runs with the neighborhood kids. He was still new at the game because he was only eight, but vandalism was in his blood. He was one of those toddlers that always drew on the walls. How was street graffiti any different?
On this particular vandalism trip, he had gone with the older kids, and they were almost done when one of the officers showed up. In a panic, Seoul caused all the paint cans to explode into colorful clouds of spray, allowing for the perfect get away. He was covering in spray paint for two weeks but it was so worth it. Ever since those younger years, Seoul has found every way to find trouble (usually with his brother Daegu). It was fun for him. He just went with the flow.
Come time for wizarding school, the Kangs were living in London. That meant the triplets would be attending Hogwarts. Seoul was easily sorted into Slytherin, where he would be right at home. Unfortunately for Hogwarts, he hasn't given up on his graffiti habit.
At the beginning of his fifth year, Seoul got into a fight with Daejeon. It took a heavy toll on the two and caused Seoul to dropout. No one knows where he is at the moment, but he still keeps in contact with his boyfriend, Siwoo.
