Talents, looks, wit - you name it. The next generation rising star Jung Woo Jin has it all. Whatever he wears, carries around & puts on, they all get sold out right after. But even he has some pain that no one knows about. He's suffering from a disease that makes him remember everything, even the tiniest details. This disease makes him feel the emotions that he had at the moment & puts him in a hell-like situation by making him re-live the past. One day, Do Hae Soo appears in his nightmare. Unlike him, she only lives with a month worth of memories.
