I began this drama with high hopes - it was set up with a premise that was something different, that I hasn't seen before.
Then as the episodes went on, it just devolved into garbage and more and more cliched tropes were introduced. They even added the (AWFUL) "met as children" trope despite this contradicting the whole premise of the show.

Actually, there were other things that didn't make sense too...like the second male lead who likes the female lead because she *look like* (but isn't) a reincarnation of his old girlfriend??
The way the storyline inexplicably fell into place with a happy ending - despite the characters receiving divine warning about disaster and punishment - just didn't make any sense either.

There are only a couple of worthwhile things about this show - L as the lead is pretty good, the actors who portray the female lead's nasty family are pretty good and the mystery about the sabotage at the dance company was interesting (I was annoyed that the perpetrators mostly didn't face any consequences though?). Also the music was pretty good (although repetitive).

Hye Sun Shin gives a decent performance as the female lead, but I think she was miscast, as her character is supposed to only be 23 and she looks her age of 30 (and was specifically playing a 30 year old in her previous series).

There were definitely some entertaining aspects of this show (I managed to watch through the whole thing), but they get overshadowed by the all the plotholes, needless annoying tropes, and melodrama; so by the end of the (overlong) 16 episodes I was just left wondering why I bothered with this mess.
