Last K drama I watched was princess hour. In my late 30s I was told by EVERYONE of my friends to watch. After reluctance, one episode, here I watched continuously for 2 days. I still kept repeat watching for tenth time. The palpable chemistry of both actors could exploded whole North korea, albeit there was very small intimated love scenes. You kept watching laughing, smiling, picking your pillow and crying whole boxed of tissues in one episode. Probably one drama like this in ten years time.
