-- STORY --
The beginning was great.
We have the shady family politics from the FL's side — the mysterious supernatural world from the ML.
Combining these two universes created an engaging setting.

For the first half, pacing was great, everything made sense and it was suspense after another.
However, the same can't be said for the latter.

They start cutting off all aspects of the show that gave it its potential. The FL's return in her ballerina career? Oversimplified. The 2ML being a previous angel was a great idea but nothing was done with it. The development of the angel world? no, but magical things continue to happen only at convenient times.

Instead, what we got was excessive montage footage of slow music, and back-and-forth 30-second cuts between our FL and ML looking at each other. I ended up watching these parts at 2x speed and it still felt repetitive and annoying. The directors wanted to force more chemistry between the two but it flopped because there was no substance in their dialogs — it's just them crying to each other that they don't want to be separated.

Lastly, the latter half really suffered from illogical events that either made no sense or were just unexplained.

The antagonists started using more drastic measures that threatened their own lives without giving them enough of a reason to do so. This is just the classic one-dimensional villain. Even worse, when they finally got caught in the media, they were still being let to roam free. Where is a proper criminal investigation for the induced car accident, which the show did identify as murder?

When the FL had a stab wound, she decided to dance instead of going to the hospital right away.

The connection of the ML and Seong Woo being the same person was a fascinating idea but nothing was really done with it, so it felt like an unfinished thought.

Things behind the deity, the angels were never explained. Perhaps this is an over-critism but the rules of what an angel can or can't do didn't seem consistent. Why did Dan's wings appear in the rain? Why did Dan turn into a human randomly? Why did Dan suddenly appear again? These were never explained.

-- ACTING --
The acting of this cast is just alright. The FL carried the most difficult role in her complex character. She indeed carried the acting for the entire show IMO. Kim Myung Soo (actor of the ML) did a good job but fell short on the performance when he was sad. He's good at the romantic eye gazes but didn't offer much for emotional delivery. Other worthy mentions are Ni Na's mother and Ni Na herself.

-- SOUND & MUSIC --
The soundtrack Pray by Klang, Oh My Angel by CHAI embodied this drama perfectly.
However, sweeter by Jess Penner (used in the fluffy romantic scenes) felt abrupt and forced every time it came on just like the scenes themselves.

-- REWATCH VALUE --
Almost no rewatch value for me. Majority of the excitement in this show were from the worldbuilding of the angels and the suspense of what the antagonists would do next, but these things are either unexplained or didn't happen within logic.
