Ryu Eun Jung, a woman with a candid personality, attracts people effortlessly. Her best friend and lifelong rival, Cheon Sang Yeon, has been by her side since elementary school. Despite coming from a wealthy background and being exceptionally talented, Sang Yeon was the source of Eun Jung's jealousy, yet they remained close, even if they sometimes hated each other.
Over the years, they drift in and out of contact, reconnecting in their teens, 20s, and 30s. Now, at 42, Eun Jung is a drama writer, and Sang Yeon is a successful movie producer. One day, Sang Yeon unexpectedly shows up in front of Eun Jung, asking her to accompany her to her euthanasia as she has terminal cancer.
