Love love this drama,its my top 5 favorite. m a fan of kim sun ah and lee dong wook so to have the collabo was awsome. He's always great when it comes to chemistry. His facial expressions and emotions says it all. I cried the last few pisodes especially when she told the mom. Junsu's ost for "you are so beautiful" is one of my favorite songs. I died in the tango scenes when his heartbeat was throbbing. must see
