Student Council President by day, absolute Boss of the nation's largest criminal organization, the Black Lotus, by night.
About
Seogang Girls' High School. Its Student Council is the most coveted student self-governing body. However, behind its glamorous facade lies a secret no one knows. In reality, the Student Council is the Black Lotus, a secret criminal organization operating in the shadows of South Korea. At the center stands 19-year-old Student Council President and Black Lotus Boss, Seo Gayeon. From Judge Seo Jiyeon and Police Commissioner Seo Juyeon to the Student Council executives, each with their own unique abilities. A world where law, power, loyalty, and betrayal are intertwined. The moment the black lotus hidden beneath the ordinary school uniform blooms, the order of the school reveals a completely different face. A girl in a school uniform stands at the pinnacle of darkness.
