On one day after Cha Dae Woong ran away from his grandfather, he accidently freed a nine-tailed fox who was closed in a painting for about 500 years. He didn’t realize what he has done, until the Gumiho (nine-tailed fox),who took the form of a beautiful woman, appeared in front of him. Dae Woong was really frightened that he ran away from her and fell on the riverbank. Since he was severely injured, Gumiho came to save him and gave him her most precious bead to share with him the mystic fox’ strength, as she owes him her freedom. Gumiho then asked him if he can help her become human and how to act like one. In return, she allowed him to use her bead for him to shoot for his dream action movie despite his body’s severe condition. 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. As time goes by, their mutual relationship grew deeper as they start to fall for each other.
