but Mi-ho will die if the bead isn't returned. Cast Main Lee Seung-gi as Cha Dae-woong Hyunwoo as young Cha Dae-woong An immature aspiring actor who lost his parents at a young age, and was subsequently raised by his affluent grandfather and aunt. When his grandfather tries to enroll him in a strict boarding school, Dae-woong runs away and eventually ends up at a Buddhist temple, where a woman's voice tells him to draw nine tails on a painting of a fox. He then meets a girl who informs him that she was the gumiho in the painting (he later calls her Mi-ho). Fearing that she would eat him, he tries to keep her happy by buying her meat (Korean beef in particular, her favorite) and hiding the fact that she's a gumiho from others. As they spend more time together, he's surprised to see that instead of the ferocious figure of legend, Mi-ho is cute and full of wonder, and falls in love with Mi-ho. Shin Min-a as Gu Mi-ho/Park Seon-ju/Gil-dal A legendary nine-tailed fox (or "gumiho" in Korean mythology) who was sealed inside a painting for 500 years. She has dreamed of becoming a human for centuries, but once rumors spread that she's a femme fatale who eats men's livers, and no human man would agree to marry her. She has superhuman strength, can run exceptionally fast, jump great heights, and can identify people and objects from great distances by smell. However, she has a mortal fear of water, since her fox bead (which houses her life energy or "qi") is made from goblin fire. After Dae-woong has an almost fatal fall from a cliff, she gives him her fox bead to keep him alive. No Min-woo as Park Dong-joo A half-human, half-supernatural being who disguises himself as an ordinary veterinarian. His initial mission was to capture the gumiho and put her back into the painting, but upon seeing Mi-ho, he changes his mind as she is the spitting image of Gil-dal, a goblin he'd once loved centuries ago, who was betrayed by her human lover and died at Dong-joo's hand. Suspecting that Mi-ho is Gil-dal's reincarnation, he acts as her mentor, watching over her and supplying her with information about humans. He also constantly warns her that humans cannot be trusted. Dong-joo tells Mi-ho how she can become human, deliberately withholding the fact that Dae-woong will die
