Kill Me Heal Me and Still 17 are great case studies on how to use KDrama tropes properly. Amnesia, childhood connection/trauma, cohabitation, 2nd lead and so on.
It is filled with plot holes and incompetent characters, but it didn't bother a bit as I was hooked on the twists and characters. Action choreography is great with actors doing their own stunts and all but the camera is shaky, too close and rarely goes wide. But at the end of the day, it is entertaining as hell. You won't feel the episode length, it passes quickly.
