I honestly can't remember. It was Either You're Beautiful or Personal Taste. I think my first drama in general (that I remember) was Tumbling. I watched it while it was airing. At the time I was obsessed with Japanese culture. I watched a lot of J-Drama before I started watching K-Drama. Back then, when I first started I didn't really know much between the two, and the site i was watching them on had mostly J-Drama. The more Korean drama I watched though, I noticed a trend. Korean Dramas are better produced, written, & acted in. They did tend to be more serious. Japanese Drama tend to be more slapstick. Now I watch Korean Drama almost exclusively. And thanks to that I became obsessed with Korean culture.
