I will admit I was drawn into this series because of Moonbin. I learned about Astro from Cha Eunwoo in his Kdramas years ago. But I also have a deep love for The Little Mermaid. I absolutely adore how this show adapted that story and expanded on it more.

Pros:
Really cool concept with the fairy tale.
Beautiful setting and costume design.
The aesthetic is clean and nice.
More seasoned actors shone despite the time and budget restraints.

Cons:
Audio was weird (I’m not sure if it’s where I watched it, but often the actors were whispering and/or the music was too loud.)
Concepts could be explored more. (I know it’s a shorter series, but if they wanted to make this a full 16 episode series it has the potential.)
Weak acting from Moonbin. (As the male lead I was expecting more and a stronger presence. Even with his character’s illness, he was very quiet and hard to remember)
Repetitive story (Main characters got drunk almost every episode. Ending is vague as well)
