Today marks the end of my twenties, a time defined by its unique struggles. Seo-eun, a stylist whose career has been going nowhere, unexpectedly finds small strokes of luck. As if to compensate for the harsh past, pleasant events begin to unfold one after another. Filled with excitement, she dreams of the future ahead... but then, misfortune rains down like a carpet bombing. Her boyfriend breaks up with her, and she's fired by her only client. To top it off, her phone, which held memories of past relationships, shatters in an instant. Ultimately, all the days of her twenties plunge into despair.
