I LOVED this show and I'll tell you why. ;-)

#1. The female lead was smart, tough, considerate but not so considerate she let people walk all over her like we see most "kind FML's" do in Lakorns. And I found her to be super beautiful in a unique way compared to other Lakorn actresses.
#2. The writing was good. The side characters were interesting and not too over the top like the majority of Lakorn side characters and I liked that as well.
#3. The "bad" guys were bad and did horrible stuff and we had the normal, jealous, spoiled, do-horrible-stuff-to-get-my-way characters, but they ended up differently than most Lakorns. I can forgive a LOT when watching a Lakorn because I know what to expect but one thing that rubs me the wrong way is how EASILY the bad guys get away with stuff and/or are forgiven like they didn't try to murder/rape/poison/whatever anyone in their path. I HATE how a ton of Lakorns play this off at the end. THIS drama didn't do that as badly as most and it was refreshing.
#4. The male lead is adorable and the acting across the board was pretty good!
#5. I really enjoyed the romance and the slower pace in this one. It felt real and beautiful and, aside from our ML's penchant for being "so good" that he did stupid self-sacrificing stuff, I felt the romance was perfect.

Need I say more?
