Taehyun Choi shares a home with his older sister, Hakyung Choi. At first glance, their lives seem ordinary—Hakyung excels in her career while Taehyun struggles academically. Everything shifts when he stumbles upon a shocking truth: they aren’t actually related by blood. Determined to confront her, Taehyun’s plans are derailed when Hakyung is involved in a tragic accident, leaving her with no memory of their past. As she slowly recovers, their bond begins to evolve in unexpected ways. What was once a simple sibling relationship now carries deeper, more complicated emotions. Without her memories, Hakyung sees Taehyun in a new light, while he grapples with his own conflicted feelings. The accident forces them to rebuild their connection from scratch, blurring the lines between family and something more. Their shared history, now erased, leaves room for a different kind of future—one neither of them anticipated. The accident becomes a turning point, transforming their dynamic forever. What was lost in memory might just be replaced by something far more profound.
