Jung Hui Wan is a 24-year-old woman who doesn't have the will to live. She lives her life as a recluse. One day, her childhood friend and first love, Kim Ram U, appears in front of her. He died 6 years ago and is now a grim reaper. When Ram U was alive, they were best friends and also had feelings for each other. Due to their own reasons, they did not tell the other person how they felt. An accident then caused Ram U's death. Now, Ram U tells Heui Wan that she has only 1 week before she dies. He continues to tell her that if she wants to die peacefully, she needs to call his name 3 times. Hui Wan, who lives a lonely life, doesn't want to separate from him again and does not call his name. Ram U gets her to make a bucket list of things to do before she dies, and they carry out her list together.
