Cha Dae Woong accidentally releases a gumiho, a legendary fox with nine tails that eats the livers of humans. He meets a pretty girl who is the gumiho he released. When Dae Woong finds out about what he did, he must try to keep her happy and hide the fact that she is a gumiho from everyone. As the story goes on, the legendary gumiho (later called Miho) wants to be human. Miho is informed by a veterinarian named Park Dong Joo (who is also not a human) that she must drink his blood to become a human in 100 days while Dae Woong will now have to keep her magical marble that lets Miho do incredible things. Moreover, Dae Woong will not be able to date anyone else but gumiho within the 100 days. However, Dong Joo doesn't tell Miho that in 100 days, Dae Woong will die if he gives the marble back to her.
