The most boring kdrama I watched. People only like this drama due to the casts. It has good potential for a good storyline but bad execution. The story derailed after they start splitting up the story to the love triangle story about 3 side characters which has no connection to the main story. It's like a big chunk of filler story. Totally unneccessary sidetrack that took half the time. No meaning to that sidestory too. This brought the story down to 2 from 4 stars. There is emotions on the main story (2 main cast). This prevented it from going to 1 star. The show is 90% character building, 10% plot. It would've been better if this is a 8-10 instead of 16 episode drama.
