Original: 내 여자친구는 구미호
After meeting a mysterious yet very beautiful girl, a wannabe action star discovers that she's, in fact, a gumiho – a legendary fox with nine tails.
Dae-woong dreams of becoming a famous actor. Mi-ho dreams of being set free. The two meet by chance when Dae-woong unwittingly frees her from the painting.
With nowhere to go, Dae-woong is stuck with Mi-ho, who wants to be human in exchange for giving Dae-woong her magic orb.
Dae-woong finds it hard to balance his new relationship with Mi-ho and his other female friends. Mi-ho must constantly remind Dae-woong about why he's still alive.
Away from Dae-woong, Mi-ho's magic starts to fade, and she begins to return to her natural form. Dae-woong has a change of heart.
Dae-woong believes that Mi-ho has left him and taken the magic orb. Believing he's free, he moves back into his grandfather's house.
Dae-woong and Mi-ho begin a relationship to cover their special situation. Mi-ho starts to become more human.
Dae-woong is forced to choose between Hye-in and Mi-ho. Mi-ho gets her first "human" job, and Dae-woong's new action skills get praise from his director.
Dae-woong begins to question his feelings for Mi-ho. Hye-in becomes suspicious about how Dae-woong and Mi-ho met.
Hye-in continues her investigation on Mi-ho and Dae-woong's relationship. Mi-ho has yet to tell Dae-woong that she is becoming human and is losing her powers.
Hye-in discovers Mi-ho's secret and threatens to tell. Mi-ho tries to leave Dae-woong to avoid the rumors.
Hye-in plans to make Mi-ho jealous. Mi-ho realizes she must learn to live without Dae-woong.
After Dae-woong confesses his feelings to Mi-ho, Dong-ju's suspicions about Mi-ho prove to be more than coincidences.
With their days together numbered, Dae-woong and Mi-ho set out on a romantic date. Dong-ju convinces Hye-in to try to keep Mi-ho away.
Mi-ho and Dae-woong decide to take matters into their own hands, but they are unsure if their plan to save each other's lives has worked.
After breaking things off with Mi-ho, Dae-woong begins to regret his decision. Mi-ho prepares to begin her new life with Dong-ju as Park Seon-ju.
Mi-ho reveals the secret she's been keeping from Dong-ju from the start. Dae-woong and Mi-ho's love for one another may prove to break the curse.
