Draxons was a gang of four boys-Yeonjun, Beomgyu, Taehyun, and Huening Kai-who had been together since high school. They were all in their twenties and had auditioned to join the Choi Mafia, the most dangerous and wealthiest mafia family in Seoul. The boss of the organization was Choi Gong-Yoo, a 46-year-old cruel-hearted man with two sons: Choi S.Coups (29), the older son, and Choi Soobin (17), the younger. One night, Draxons attended a party at a bar, a place mostly frequented by drug dealers and thieves. While the three were busy flirting with girls, Huening Kai's eyes landed on a specific young boy-one who wasn't drinking and sat alone, without a chick or any friends. With a firm smirk, he approached the boy, intending to mess with him. However, after the boy rejected Huening Kai's offer, the spoiled gangster went to fetch his crew so they could bully him. Little did they know, the boy was the son of their future boss.
