A werewolf hunter named Choyoon must hunt vampires. While infiltrating a club to capture his target, the vampire Jisle, he unexpectedly finds himself captivated by her. After a chance encounter that leads to a single night together, Choyoon tries to cleverly approach Jisle, but she is already far above him, making it impossible for him to reach her. Jisle, a vampire with unique blue-hued odd eyes, has lived a lonely life. Despite looking down on the insignificant wolf that suddenly appeared, she gradually finds herself falling for Choyoon's cuteness. This is a story of two individuals, initially meeting as hunter and prey, who go through various conflicts and ultimately fall in love.
