Ko Hye-Rim (Han Ye-Seul) is a famous fortune-teller. She is known as "Madame Antoine" and insists that she is spiritually connected to Marie Antoinette, but that part is a lie. She is able to see through people's stories due to her intelligence and keen sense. She dreams of having love in a romantic film.

Ko Hye-Rim then takes part in a psychological test project conducted by psychotherapist Choi Soo-Hyun (Sung Joon). His goal is to prove that true love does not exist. Coincidentally, the name for his psychological treatment center is Madame Antoine.
