I came into this drama without seeing the Taiwanese version and without knowing any of the actors (except for falling for secondary OTP in boys before flowers with KHJ). I have no bias towards KHJ other than the guy sure can make your heart skip a beat when he smiles :) I have to say this drama is a hate/love one for most who watch it and I fall in the LOVE side. The things that bugged me in the first 2 episodes quickly got fixed/removed (like her daydreams) and from then on I was hooked. This drama has a very lighthearted and BASIC story line people so don't expect great turmoil and over the top romance. Its a simple love story that can truly happen..no crazy twists that make you go "only on TV". What really hooks me in this drama is the cute/embarrassing moments that happen to Oh Ha Ni that make me cringe and giggle and hide behind my blanket for her sake. I love love that feeling in rom-coms and this drama has so many of them!! Jung So Min plays Oh Ha Ni so perfectly, if it weren't for her I'm sure I wouldn't have continued on with the drama. I love a good drama like everyone else but I love me some silly too and this drama does silly without being stupid-silly (a fine fine line that's usually crossed making me drop a drama). It may seem crazy from our point of view that this girl is non-stop stalking our poor Baek Seung Jo but just when you think she's going too far, she holds back and restrains herself and just when you think she's gonna get over him, he shows her signs of hope and she's back to her obsession again. I know a lot of people seem to hate it for the silliness and some people can't seem to get over the differences in PK versus ISWAK but all I can say is if silly bugs you and if normalcy bugs you then this drama may not be for you. I think its because I like J-dramas so much for the silliness and this drama was supposedly a straight adaptation of a Japanese manga that I am used to and enjoy that silliness. If you didn't like ISWAK don't ignore this drama because I couldn't watch past 4 episodes of ISWAK (I tried so many many times but I can't get over how weak the female character is in that one) and I still love this drama.
