Story

Tak Dong Kyung (act by Park Bo-young),an editor for a web novel company. She finds out that she has only 3 months to live because of glioblastoma.

Myul Mang (act by Seo In-guk), a messenger between God and humans, suddenly appears in her ordinary life. He was born between the dark and the light: when he breathes, countries disappear; where 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.

Dong Kyung makes a 100-day contract with him, risking her life and her love. Myeol Mang eventually forms a relationship with her, who curses the whole world, as she drags him into her life with her fierce desire to live.
