The chemistry between the leads is really good, there are a lot of sweet moments between them and several funny moments provided by the female lead. It is hard to pick only one thing that I like about this. I liked almost everything. If you enjoy a good amount of romance and comedy, adding to it time travel, a "dont you dare mess with me" female lead, a hot/sweet male lead plus beautiful scenarios and clothes; then there is a high chance you will like this. There is also fantasy, specially in the second half. I kept checking everyday for new episodes. Usually I dont start a drama till it finishes airing, but I did the "mistake" of watching the first episode and then couldn’t help but watch the new episodes as soon as they came out. Although I liked it, I felt the ending was a little rushed and the fantasy part made me cringe a little since I am not a big fan of the genre. For me it’s a 9/10. The only other drama that I gave such a high rating was Empress Ki. I will definitely rewatch this. Actually I watched some of the episodes 2 times already since I watched first alone and then with my sister.
