"내 여자친구는 구미호 (My Girlfriend is a Nine-Tailed Fox)" is a comedy and romance series that aired Wednesday and Thursday nights from August to September 2010 starring Shin Min Ah, Lee Seung Ki, Park Soo Jin, No Min Woo, Hyo Min (T-ARA), and more. This series revolves around a lengendary nine-tailed fox (Shin Min Ah) who tries to become a human. She failed to become a human once because she was unable to meet the requirement of finding a husband, and has since been trapped inside a painting for 500 years. One night, Cha Dae Woong (Lee Seung Ki) accidently releases the nine-tailed fox from the painting, and suffers a life threatening fall while fleeing but was saved by the nine-tailed fox when she gave him her fox's bead. After being released, she continues her goal of becoming a human. Park Dong Joo (No Min Woo) who is half human half monster, told her in order to successfully become a human she must drink human blood and allow a human to keep her fox's bead inside their body for 100 days. What he didn't tell her was that after 100 days, the human will die.
I really like this series, one of my favourites from 2010. If you haven't seen this yet, I would recommend it.
