Housewife Ayaka (37 years old). A stay-at-home mother with no children, her daily life is dull and suffocating. Nine years into marriage, her husband's presence has faded, and loneliness continues to grow. Amid this emptiness, a two-day, one-night trip with a man she’s just met begins to shake her emotionally. Over the course of 24 intimate hours, she starts questioning her bond with her husband and resolves to embrace new feelings. "I thought I’d already made up my mind..."—these words symbolize her inner turmoil. Tired of repeating the same monotonous days and having lost confidence in herself, she gradually rediscovers her true self through this new encounter.
