Shin Ji-hyun is a bubbly, naive young woman who has it all, but her perfect life is shattered right before her wedding by a tragic car accident that leaves her brain-dead and in a coma. Because it wasn't her time to die, an afterlife guide known as the "Scheduler" gives her a second chance.
The catch: within 49 days, she must collect three pure teardrops of genuine love from people outside her bloodline. To do this, she is allowed to inhabit the body of Song Yi-kyung, a profoundly depressed convenience store worker who unknowingly caused Ji-hyun's accident. While borrowing Yi-kyung's body, Ji-hyun uncovers shocking secrets—including a malicious affair and a corporate conspiracy plotted by her fiancé and closest friend.
