Only 4 episodes have been aired, and I've enjoyed them quite a bit so far.
The setting is comfortable and the characters are fun. Like another reviewer mentioned, no annoying personalities have showed up, at least not yet. The aunt has the potential to become annoying but she has mostly been amusing till now.
I like the humor - it's not over-the-top and not based on stupidity, like in many Korean shows.
There's only one thing which bothered me: how could the aunt "sell" our female lead to a fish farm without her consent? It seemed to be a type of slavery on some island. Why do they all just go back to normal? Is it some sort of vet duty? It must be some local cultural reference that I'm missing.
Edit: sadly, I have to remove a few stars now that I have watched the full series.
As the story develops, I was becoming more and more incredulous. Based on the opening episodes, I've settled for a cosy small town mystery with cute animals--only to find myself watching a grim, mass murder rampage.
It's not the first time that a Korean drama does this complete genre switch on me. I can't say I like it. In this case, I just can't mix "light comedy" with "killing spree."
The last 2 episodes are just farcical.
