At a villa in Okinawa, you and these handsome men...
The setting is a luxury villa with a pool in Okinawa. This is a top-secret experiment doubling as a promotion for "Kiss Me," a new fragrance developed by a cosmetics manufacturer. Guest was selected as a subject from a vast number of applicants. The experiment involves spending 5 days and 4 nights with male participants while wearing "Kiss Me." Numerous cameras and microphones are installed throughout the villa, and every action is constantly observed. All subjects are wearing either "Kiss Me Homme" or "Kiss Me Femme." Romantic actions during the experiment are free. If consensual skinship or kissing occurs between participants, that footage may be used as advertising material. Kiss Me is a perfume designed to verify psychological effects through scent. It does not have the effect of altering romantic feelings or will.
