In a world where retired grim reapers and other beings from the afterlife live as immortals cursed with purposeless lives, former Angel of Death, Jung Jae-Hyun, has wandered for centuries, lost in a fate-less existence. When he stumbles upon Lee Hee Young, a joyful café owner who radiates warmth and kindness, he senses something different about her—something that could break his curse. Initially seeking to use her, Jae-Hyun soon finds himself torn between exploiting her divine blessing and protecting her from the dangers it attracts, as unexpected love begins to bloom between them.
