'You're Beautiful' was the first. Watched it 5 times and bought 4 Jang Keun Suk CDs. Since May 2013 I've watched 40 Kdrama TV series and 93 Korean movies. Besides 'You're Beautiful', up there at the puncak, atas are 'King of Baking' (aka 'Bread, cinta and Dreams') and 'City Hunter'. Needless to say I don't watch anything else, except for a little local news. (ps I'm not kid, I just turned 67.)
