At 43, she shares a happy home with her husband, who holds a managerial position, yet their relationship has grown emotionally distant, leaving her craving excitement. For her, the monthly appreciation gatherings she hosts at home for her subordinates have become a special escape. These meetings are her only chance to interact physically with men outside her marriage, and her younger coworkers admire her deeply as a woman. Snow-hue, who's always been popular with younger men, begins reminiscing about her past flirtations. Then one day, confessions from a 27-year-old employee and a 23-year-old new hire awaken desires she can no longer suppress.
