While Eun Seon Woo (Jung Il Woo), the head of the lucrative Eunkang business group empire, appears to be just another silver-spoon family heir, he secretly moonlights as the head of a private detective office. A master of disguise with unparalleled athletic prowess, he also has keen powers of deduction. Meanwhile, Don Se Ra (Kwon Yuri) is a young woman with incredible vision. Like Seon Woo, she wants to keep her talent a secret, so she wears thick glasses to hide her skill. A lifelong altruist, she has dedicated her life to helping others. When she meets Seon Woo, they decide to put their skills together to solve crimes. But when they start to fall for each other, will their budding partnership deepen, or careen off the rails?
