I had hard time with deciding to watch it, still happy that in the end I choosed to give it a chance. It is typical rom-com while actually not at all. There is mistery, comedy, cute scenes - not boring at all and very chaotic. Krystal played perfectly and her chemistry with Kim Jae Wook was great.
Even my mother watched this - in two days, eventhought that she had work during that time, sleep was not as important as to watch this and she is not someone who will choose a kdrama to watch.
Definitely worth watching.
