'My Girlfriend is a Gumiho' is a south-korean drama, aired in 2010, starring Shin Min-ah and Lee Seung-gi. It is translated as 'My Girlfriend is a Nine-Tail Fox'. 

[Note: A gumiho -or nine tail fox- is a legendary fox that, after living thousand years, become a demon in the form of a fox with nine tails. It can transform into other creature too, like humans and mostly beautiful girls that seduces men and eat their heart or lives. ]

Shin Min-ah is the 'Gumiho' itselfs, in the begin of the story she is sealed inside an ancient painting in a temple. Then a clumsy boy, Cha Dae-woong, played by Lee Seung-gi, unintentionally frees her. Since he's scared he escapes but doing so he falls and nearly dies, what saves him is non others that the Gumiho. 

The next day he doesn't remember a thing but finds a pretty girl in a white dress following him. Cha Dae-woong thinks he's lucky but he'll soon change his mind..The girl really follows him everywhere, to his university till his home. She then claims to be the Gumiho that he freed and that she saved his life.

Of course he doesn't believe her and just think she's crazy, so he does everything he can to keep her away.  Then to prove it she's a real gumiho, on a full moon night, she shows him her real nature -that is to say her nine tails-

After that he lets her stay with him and tries to make her happy, all that while hiding to others her true identity. On her part she doesn't know anything about modern society- and she likes Dae-woong so she follows him around. After a little while we get to know Mi-ho -that's how Dae-woong call her- past. She was in love with a man and wanted to live with humans, but he betrayed her. Even after that she still wants to live in the human world and act like them. Her story is just so sad and she really comes off it as super cute and pure.

Well, obliviously a drama is no drama wihtout some antagonist. So we have Park Dong-joo, an half-human that tries to bring Mi-ho back to the painting, so he pursue her while pretending to be a kind veterinarian. After a while he finally understands her reasons and tells her who to become an half-human, that is to say she has to make so Dae-woong keeps her bead within him for 100 days, enter a 'Love Contract' and keep the bead from being harmed by remaining chaste.

However by doing so, after 100 days the human will die. But Dong-Ju doesn't tell her about that, nor does he tell her about his past or reasons.. we'll find out about that much later.

Finally, Mi-ho and Dae-woong fall in love. They don't know anything about the truth, if Mi-ho becomes partly or full human he will die.

They just live happly, being cute, as he tries to break-out as a action actor and film-maker. What will happen after that? Will he be safe and will she manage to become human? Well, for that, you have to see the drama.

I know you'll love it as much as I did. I hope Shin Min-ah and Lee Seung-gi will do more movies and dramas together because they have such a great chemistry and are so cute! Obliviously there are a lot of characters, I just named three because they were the most important, but you can find out about the others -and the actors- here. 

This is singed by Lee Seung-gi himself.  

 This is by Lee Sun Hee, the 'fox' theme.

So, please, definitely watch 'My Girlfriend is a Gumiho'!
