I loved watching it. It was unique and the fact that the girl is independent and strong makes me love it even more (and also the fact that she is the main female of The Sleepless Princess). It is a time travel series that anyone will love because it doesnt contain a lot of betrayal and hatred which is why its perfect if you want to take a break from the classical dramas. It was like a breath of fresh air. The girl is so cute because although shes human whenever the guy teases her, she acts like a cute little kitten. HOWEVER, the ending was horrible. It was not pleasant to watch the ending. After the ending I decided to make another up in my head which is : !!Slightly Spoiler!!
!! If you continue you will see my own made up ending which hints the original ending!!

The girl will grow up super fast so that they can be together in the end
