This drama started airing on the first day of the year and it began with a bang. The story and sequence of events were gripping and held my rapt attention for weeks. I enjoyed the ride so much but my experience dipped towards the end. I imagine that having to wait between episodes contributed to that. But overall, an incredible showcase of acting skills. The four lead actors were spectacular - their characters are unforgettable. I loved the fact that our ML, Yu Ji-Hyuk is not the typical good-two-shoes 'green flag' love interest with no discernible flaws. He is generous and attentive but he can also be ruthless, and he doesn't shy away from that fact. And the 'master villain'? I have to give her a shout - she had me worried sick. A truly terrifying character portrayed excellently well.
