With high expectations before I started, this did not disappoint. As what Ms. Bo Ah said in an interview there was no dead scene as they unite fantasy, action, and melodrama. And that was true, I was not bored for a second - I even rewind some scenes because it was too much to handle lol.

As for their acting, there was no problem at all. All of them were skillfull!! CG + Acting = it was flawless and superb.

The plot was written and executed well. The pace was good, it was not too rapid nor slow; nor crammed (unlike that fantasy drama).

The flashbacks were not irritating. However, I felt that there were some gaps, they just showed the essential events.

As per the characters they were portrayed sufficiently. I comprehend the point of view of each character understanding why they were able to do such decisions.

The music? Mate, they were not joking. There was this BGM and it will keep playing in your mind! The OSTs will also give you the feels after watching the drama I can assure you!

Personally, this is an incredible, terrific, extraordinary, and remarkable drama for me. This pierced my heart! It is now renting my heart for free.
