My Girlfriend Is a Gumiho

With dreams of becoming an action star, Dae Woong escapes from his grandfather, who wants him to go to college, and ends up in a dark temple.

Mi Ho takes away the power of the marble she gave to Dae Woong. Mi Ho then coldheartedly tells him that she wouldn't save him because he betrayed her.

Dae Woong shouts at Hye In, who thinks that Mi Ho is his girlfriend. Meanwhile, Mi Ho is surprised to hear from Byung Soo that Dae Woong likes Hye In.

Mi Ho gradually loses her strength as Dae Woong -- with the marble -- gets farther away from her. She tries not to cry, but she turns into a fox.

Dae Woong goes looking for Mi Ho, but he can't find her anywhere. He soon shouts with joy that she is gone and rejoices in his freedom.

Dae Woong and Mi Ho make a contract to be boyfriend and girlfriend for 100 days. Soon, Dae Woong notices she wants to marry him and tells her to stop.

Dae Woong tells Hye In that, for now, he has to stay with Mi Ho. Meanwhile, Mi Ho feels sorry for Dae Woong.

Dae Woong and Mi Ho go to the movie theater. There, Mi Ho sees a lot of couples snuggling together and she tries to do the same thing to Dae Woong.

Grandfather tells Dae Woong to come back home. Later, Mi Ho suddenly feels a lot of pain and discovers that one of her tails has disappeared.

Mi Ho, not wanting to disappear from Dae Woong, goes to Hye In and tells her about the beads and how much she wants to stay.

Hye In plots to make Mi Ho jealous, and Mi Ho realizes she must learn to live without Dae Woong.

Dae Woong and Mi Ho finally know how they feel about each other. Mi Ho makes plans for what she wants to do when she becomes a human being.

Dae Woong and Mi Ho enjoy a normal date. Later, Hye In tells Dae Woong that maybe Dong Joo and Mi Ho are planning something dangerous.

Dae Woong tells Mi Ho that in order for both of them to live, right at the moment when half of the 100 days have passed, they should kiss each other.

Mi Ho visits a wedding shop with Dong Joo. She tells Dong Joo that Dae Woong will be all right if he sees her married to someone else and living well.

Dae Woong is surprised to learn that Mi Ho has only one tail left. She tells him that she still wants to become human and she will stay with Dong Joo.
