This drama was definitely addictive and fun to watch. The creepy serial kidnapper/murderer storyline was particularly interesting . The villain did a great job with his role. Park Bo-Young was so loveable and adorable. The juxtaposition of her tiny frame with her immense strength was amusing and entertaining, and very well done.
The romance was also very sweet and I actually cried for Guk-doo. The dynamic between the leading triad was done very well. Park Hyung-sik also did a phenomenal job and I couldn't help but fall for his exaggerated expressions and antics.

What let this drama down were the comedic sub-plots. I resorted to skipping many of the scenes with Baek Tak Party and its members, which in my opinion got way too much screen time in the last few episodes. They served their purpose well in terms of providing people for Bong Soon to beat up, but otherwise added nothing to the story. Similarly with the doppelganger Mr Oh at Ainsoft - I skipped many of his scenes too because they were distasteful and unnecessary. Because of these side characters, the storyline felt like a restaurant menu with too many options. The drama could have benefitted from a strong editing hand and less characters.
