LIE TO ME (watched it on Netflix 1st - I liked it, but then I never watched Kdramas for about 2 years, simply did not have time, but when I got back to it, I could not stop now.... simply addicted!) By the way, this drama has been the most watched for me. Reason: romance chemistry hit me in this one and for me that did it!
when i returned to Kdrams BOYS OVER FLOWERS was the one I watched next. I loved it at the time. Rewatched it 2x in a row. I did not like the main actress but all the F4 boys did a good job, and Lee MinHo was good in there. At that time I was back to Kdramas and became addicted with K-dramas and T-dramas afterwards.
