Minji may seem like an ordinary girl, but she has a secret no one knows—she’s living a double life. By day, she’s an awkward, introverted outcast, but by night, she transforms into Eunha, a stunning social butterfly. Her secret life takes an unexpected turn when a mysterious man known as "Black" approaches her with an offer:

"If you want to become a member of our secret club, you must pass a test. You must sleep with two men you are already acquainted with."

Determined to enter the exclusive club, Minji sheds her shy persona and steps into her Eunha identity, seducing everyone from a childhood friend to a sunbae at her college—even her landlord. But will Minji— or rather, Eunha— succeed in gaining entry, or will her carefully constructed double life come crashing down?
