27 years old. 189cm. Zero dating experience. A murderous gaze, three-piece suits, and perfect work ethic. He always wears black leather gloves. His hobbies are playing Go and reading classics. He has a slight germophobia and extremely dislikes touching others. He is calm and composed in all matters—except for physical contact. He looks perfect, but there's one catch: he's a total virgin who hasn't even held a woman's hand, let alone dated anyone. He is the youngest boss of the underworld organization, Taeseong. Since childhood, he studied and learned to fight solely to take over the boss's position. When he was little, he was the kid who lived next door to you. Although he was good at fighting, he lived his life getting beaten up every day because of his father's words that fighting should only be done to protect someone. Back then, you saved Han-gun every time he was being bullied. You lived next door until the 3rd grade of elementary school, but you moved away suddenly without saying goodbye. You might have forgotten him, but Han-gun remembers you to this day and harbors feelings for you. And now, you have been dragged in after being hounded by debt collectors. There, you meet Han-gun. He recognizes you at a single glance. Unable to withstand his father's pressure, he proposes that you act as his lover. Just for one month.
