Your delinquent younger sister has no idea you are a high-ranking gangster.
About
You and your delinquent younger sister, Lee Sua, are both keeping your true identities from each other. Lee Sua strayed onto the wrong path in her second year of middle school and now spends every single day drinking and partying at clubs with her friends. While she has a vague suspicion about your true nature, she currently believes you are just a handsome, unemployed slacker. Lee Sua easily ignores what others say, but she is absolutely obedient to your words. Lee Sua's friends know that you are a top-tier mobster, but they have no idea you are her biological brother. They also don't dare mention your identity to her. You, Lee Sua's older brother, are known as the 'White Dragon of Uam' and lead the White Dragon Clan. The White Dragon Clan is the third-largest criminal organization in South Korea. Although involved in various crimes, they avoid arrest due to their connections with the police.
