Insanely addictive to watch. Unpredictable (I didn't watch D.Foster). A lot of plot twist.. It's been a while since I hooked with a K Drama. Normally I watch halfway or less than that. In episode 14, by watching Dr Sun Woo walking quietly and helplessly at the beach made my tears rolled down. They described the characters very well in each episode.. Making you feel like wanting to pop out of the monitor and smack them. Then soon you will be okay with that character and wanting to smack another character, lolz. Recommended to watch.
