A modern-day “Prince and the Pauper” revenge story in which a poor job-seeker, who barely secures a position at a company, is fired and even goes to prison on behalf of the owner’s heir simply because they look alike. She then joins forces with other underdogs (“Eul”) to overthrow the “king.” The drama follows the journey of a once-kind ordinary citizen as she navigates the gray area between good and evil, delivering thrilling battles, romance, and the rise of a villain we can’t help but root for.
