Tak Dong-kyung (Park Bo-young) lives an ordinary life who works as an editor for an awful boss at a web novel publishing firm. On the anniversary of her parent's death, she learns that she will die from a glioblastoma in three months, her boyfriend was actually married with a pregnant wife, her younger brother is once again irresponsible, and has to deal with a pervert on the subway.
Deciding to drown her sorrows in soju, she happens to see a shooting star from her rooftop apartment and drunkenly wishes for the world to be doomed. Her atypical wish is heard by Myul Mang (Seo In-guk), a messenger between gods and humans. He was born between dark and light: when he breathes, countries disappear; when he walks, the seasons collapse; when he smiles, a life is extinguished. All he has to do is exist for something to fall into ruin. This is not his intention but simply his fate. On his birthday, he gets to choose a human's wish to fulfill. Sick of his fate, he chooses to fulfill Dong-kyung's wish to end the world.
Dong-kyung ends up signing a hundred-day contract with Myul Mang, risking everything she has ever known.[2][4]
