I was a bit disappointed at first, I found the first 5 episodes a bit boring . However by the time we reached episode 10 I was over that and I started to dread the moment of the inevitable reveal, but I was pleasantly surprised when that moment came (very late in the series), because the revelation drama/conflict had gotten resolved swiftly and the resolution was very beautiful and unexpected. Throughout the entire show I was waiting for various terrible things to happen, but they were only teased, none of them came to be. (such as extreme love triangle plots, forced separation, or strong rivalry induced melodrama) This is one of those shows that's about enjoying the journey, rather than anticipating the end. I really liked the character interactions, the comedy and the main leads had great chemistry, the entire cast was amazing really. Having watched Legend of the Blue Sea I kept thinking how much better Shin Hyesun could have been at being a hapless mermaid, I like Jun Jihyun as an actress, but that mermaid character was nearly identical to this 30 years old teen character, but it's blatantly obvious whom this role fit better.

The OST was awesome, not at Goblin levels, but not much worse really.
