WHAT I LIKED:
- The main couple: I thought the two of them were both goodlooking and cute together. It was nice that there was no rival and they both quickly fell for each other. No angst because of misunderstanding and they basically spend the drama discovering each other's story, sharing cute and romantic moments and supporting and helping and saving each other.
- The story: I thought the story was clear and well developped between the different investigations. Some investigations were linked to the main plot some were not but overall the pace and writing was good enough to make sub plots and plot interesting without being gripping. You don't end each episode with a cliffhanger and dying to see what is going to happen but most episodes were enjoyable.

WHAT I DID NOT LIKE:
- The secondary couple: They were both cute and nice persons and helpful but I felt that they had no other meaning but to be sidekicks. The SML was a bit simple minded and he lacked depth until the last eps were his character took a bigger dimension. The SFL had absolutely no character development and her background was very unclear so beside her poisons she looked very bland. Their love story really suffered from the comparison with the main couple's one.
- The villain: He was a little bit too wordy and did not get his hand dirty while his lackeys were eliminated one after another so he looked not so mighty but rather annoying.
- The drama lacked of punch as most of the time the leads did not look really endangered or challenged.

OVERALL:
It is a drama which does what it has to do: entertain with a consistent story and some sub stories to develop and support the characters. There is a good dose of romance and cute moments too. An OK drama to watch when you are bored. A very decent cdrama with a nice ending I appreciated after watching the Heiress.
