Watched it while it was on-air. I really loved it in the first half. It really had potential to be a masterpiece, if they kept the original plot as the webtoon, which was already very popular at that time.

But they ruined the series in the worst way. They changed the original plot and without asking the author and cut Park Hae Jin (the male lead) out of the series and replaced his scenes with the unknown second male lead's, while Park Hae Jin was the reason why a lot of people watched this series when no-one else in the cast was well-known back then.

The author and the series's fans got so angry back then, including Park Hae Jin who was also a big fan of the webtoon. But I can't rate it 1 at least for Park Hae Jin's efforts. Then to make up, the author asked Park Hae Jin to remake the webtoon into a movie version. But it's not the same. So sad for a supposedly great drama.
