This drama was most popular over seas rather than Korean and the reason I do not know. Me living in the U.S I loved it along with all my friends who saw it we fell in love with it and not just because of Jung Yong Hwa but because the cast was incredible with him and Park Shin Hye who are amongst my favorite actors. This drama was very good to me because I am one of those people who watches a drama once its finished and all episodes are online but this one I made the mistake of watching when it barely came out and had to wait to see it after every week. I hated having to wait I like to finish dramas at most a week for the long and not so interesting ones but the awesome ones like this one I love to watch in 2 days. The OST is all in my i-pod and laptop so the music is awesome as well. I Love Heaartstrings!!
