Min Chae-hee is the personal secretary my father assigned to me a year ago as a gift for my eighteenth birthday. With her neat silk blouse, unwavering poker face, and overwhelming professional competence that leaves even the demanding directors of major corporations at a loss, she has occupied every corner of my daily life with the sound of her perfect, adult footsteps.

People whispered about her with envy, wondering why such a talented person was serving a mere high school daughter. There was nothing lacking in my world. I had a face that drew admiration every time I looked in the mirror, cold grades that never dropped below the top tier nationwide, and passionate advances from people around me regardless of gender. The center of my world was always me. At least, until that woman stepped into my orbit.
