Miyazaki Ayaka is a 39-year-old single milf who values her career and lives confidently on her own terms. Having never seriously considered marriage, she has always stayed true to herself, but lately she's begun feeling a bit uneasy as conversations about marriage with friends have gradually faded. One day, she reunites with her old college circle friends for a long-overdue drinking party. Though Ayaka rarely attends casual mixers, she eagerly accepts this special chance to reconnect with her former peers. However, she soon realizes that all the attendees—aside from herself—are men. The lively conversations with these familiar faces bring fresh excitement into her life, reigniting her self-confidence and slowly awakening romantic feelings she thought had long been dormant.
