This is a classic. If you want to LOL you got it in spades here! But if you are over a certain age, I would avoid as it seems orientated towards a younger audience, painfully so! This is an early offering from the Hong sisters and their second time working with Lee Seung-gi, who looks very young here. The beginning starts off strong but then, not even at the half-way point it starts to flag and bring on the tired Kdrama trope of male love interest acting as a father figure to female love interest acting as his daughter (at 5yrs old!) We have very young, recognisable leads, acting cute here in an exaggerated manner. Towards the end I just wanted it to end as I wasn't that invested by then. I enjoyed the OST. Instantly recognisable catchy tunes for each character. The second couple got my vote for being over 40, having a past dating history, meeting under comical misunderstandings and achieving a happy ending. We have the familiar 'Little Mermaid' tale popping up here too...I mean there are lots of other fairy tales out there. I don't really understand the Kdrama obsession with this one. There are glaring inconsistences but hey it was made for children so just leave them to it! CUTE!
