Have you ever have that feeling that you've seen that someone before but you just can't place where? As a Korean drama addict, i feel happy whenever i see actors and actress, even though i can't remember or memorize their name, and know what drama I've seen them. Last night I started watching Dr.Frost and i know I've watched him from somewhere.

And after googling, I can't sleep if something, even as simple as this, keeps on nagging on my mind :-) He is Song Chang-eui and he is Kim Suk-hyun in Heartstring, the Broadway composer-turned-music director. And now he's playing Dr. Frost. So now i know.
