A 40-year-old elegant and refined concierge, Saeko Murakami. She works at a luxury hotel in central Tokyo, assisting guests with room requests, sightseeing recommendations, restaurant introductions, and theater ticket arrangements—fulfilling various needs with grace. Because of her role, she even ends up satisfying nighttime desires. Her hospitality spirit—feeling compelled to fulfill anyone who relies on her—has deeply influenced her married life. Lately, however, her husband has become passive in bed. Always giving in both work and marriage, she secretly longs to be desired and attended to more. What she truly desires is mutual satisfaction—a balanced, give-and-take sexual relationship where both partners make each other climax. Behind her pure and dignified appearance lies a surprisingly lustful side, which becomes fully evident once she strips off her uniform.
