Shihori, a beautiful dentist, has achieved both wealth and fame and lives a life of luxury, but she is not satisfied in Kokoro or body. This is due to a sexual inclination that she has always kept hidden: she can only love women. One day, Shihori is Kokoro at first sight by Yuu, an office lady who comes to see her as a patient. The two soon become intimate beyond the doctor-patient relationship.
