Note: Haven't seen the first part. I don't think you need to watch it, as it recaps everything what happened in the first part.

Watched this drama because it seemed like there would be a lot of cute scenes between the leads. If you're looking for those, I suggest skipping forward a bunch. I didn't skip as the story actually was quite interesting, but the story felt quite rushed at some points. I really wish we could have seen more scenes between the leads, as it sometimes felt like an afterthought.
The story line between the humans and superhumans was surprisingly done quite well, and even though I knew who the bad guy was before he was revealed, I do believe the reveal was done well, because I didn't feel like it was obvious nor was it completely out of the blue.
The relationships felt a bit off, as I didn't always understand character motivation, and the forgiveness for some terrible things came a bit too easy for my liking
Music: I thought it was well done, I'm on my way to Spotify to find some of the gems that were used, the music was timed very well

Why not a higher rating? Well, even though the drama itself was quite ok, there were still some points that bothered me, like the relationships between the many couples. Not a fan of relationships that have an unhealthy beginning or where one of the partners is asserting ownership over the other partner.
