Well first of all if you are an OTAKU you will surely like this drama and you'll see the actors pains and happiness.

Now for a Normal Person the actor might look to be acting extremely shy or awkward well but thats just how it is so you might have to deal with it throughout the whole drama.
But the drama is quite good and i liked it very much. I would re-watch it again. Cause im sucker for this kinda S***.
Well its not anything new that we haven't seen. Its the same pretty girl - pushover not so pretty guy love story but even still its presented in a good way.
I recommend giving it a try at least by watching the first episode which might make you hooked because of the actor he'sso good in this... oh and trust me the actress gets better after the first episode ( i did'nt like her in the first episode cause she's looking all rich, dreamy like and whatnot)
