It's a must-watch. I'm holding off until there are more than 10 episodes before I really start watching it. (Just watched first ep.) and OMG, Doctor's son (Jung Kyung Ho) is one effin hot BAMF. I swear to got, this man can cause some serious ladyboner. His acting is good and believable (but i may be biased because I fall for the bad guy gangster type too easily.)
But seriously, look!
