You're Beautiful. I loved it a lot, and it made me interested in K-pop as well. Still It's the only one I watched so far, but I already downloaded many other K-Dramas.
Iris.. I watched it like an year or something? ago and I was just getting into kpop and I was totally obsessed with T.O.P and It was dubbed in my language so I decided to give it a try and later I regretted it thousands of times bc It spread like ebola and I couldn't stop watching dramas and holy jesus I still can't т.т
I accidentally found on youtube movie Always with So Ji Sub and after I madly fell for him I searched more movies with him but I found What happened in Bali drama.So, my first drama was What happened in Bali. I watched it twice in a row. :P
The first kdrama I came across was BOF. Didn't finish it, never will. Playful Kiss was my gateway drama but Secret Garden and Coffee Prince made me stay.
