It's a really interesting series. I'm not sure why there's so low ratings given here. I've been deferring to watch this series because of the low ratings. The series came out with English translation on YouTube and I've been seeing good comments there. So, I decided to watch and am so glad I did. I'm at episode 4 and am giving this series many thumbs up! It has very deep soulful romance, mystery, murder, family matters and a superb cast with good acting skills. It's also fast paced. The only issue I notice is the big age gap between the male and female leads. It would have been a more believable story if the age gap is not so big. Sometimes it's painful to watch because the age gap shows physically and in mannerisms. But the story is so good and the acting as well such that I'm indeed enjoying the series. I must also mention that the music and song are hauntingly memorable.
