It was Princess Lulu who first introduced her to Korean dramas but it was Yoon Ji-hoo from Boys Over Flowers who enticed her to stay in K-dramaland. She writes news and features for Kdramapal, which combines two of her most favorite things in the world—writing and K-dramas (look who's living the dream). The name Luna literally translates to "moon" and nothing special; she just likes writing at night.
