I am a big fan of this drama. believe me, you will find the first episode kinda boring. but as the drama will keep going it will make you confused and build the excitement about what will happen in the next episode. It is recommended to all those Kdrama fans who love chemistry, jealousy, comedy, romance, etc.
last but not least don't judge the drama by watching only 1 ep or 2. at least watch till episode 6 and then you can judge.
