I believe it was one of the few dramas that almost stopped me from watching. At first I thought everything was very beautiful, the ost, the characters and how they were built, the story had a good start and a good plot. I was actually watching for Lee Min Ho, but I liked what was shown to me at the beginning.

Then, halfway through, everything seemed so monotonous. It was as if it was necessary to know everything about their past before the present. I wanted the now to be more developed so that it wouldn't get so lost.

At some point in history you already know who the antagonists are, you know what they are going to do, but you don't understand why exactly. You know, a lot has not been explained. The past was something different, they had their reasons, but now everything is different, people who think differently, and it seems like everyone is living in the same nightmare with no reason to do things.

I kept watching just to see the ending, although I already anticipated that it would be ok. Unfortunately I can't give more than a 7 for this drama, I thought it would impress me more because it is a story with mermaids (which I love), but in the end people are just people and what you thought would happen , it happens. No big deal.
