Had been looking out for this melodrama as it was introduced on KBS World facebook. However Astro magazine failed me (*_*) It's showing from 22 June 2013 at 1:45pm. On weekdays it is on Mondays and Tuesdays at 9pm. Repeats same days at 2:15pm and 5:05am.
The lead actress is Son Yeh Jin who was in Personal Taste with Lee Min Ho. Don't Look Back : The Legend of Orpheus is also known as Shark. I'm already liking it from Episode 1 (^_^)
