Fish upon the sky - somehow a comedy with romantic twist.
"Comedy" - depends on your personal taste;
"Romantic twist" - the plot is something we've seen before, but it was done with engineers, nothing special and kind of predictable, but still interesting to watch.
Honestly I wanted more from the story, there was potential, but it ended up in the same canal with the other series from before( love triangle, coming out, walking in circles)
The production was alright, the music not so much.
The actors did their job nicely, being their first time.

Not a bad series but depends on your personal taste. I think you are going to like it, if you are looking for a easy to follow story, good looking actors and somewhat alright plot.
