I believe that the cast really needed to improve their acting skills or rather should I say, they should of put more feelings into someone of the senses they played that needed that powerful emotional expression. I mean I've read the manga and when I compare someone of the senses I would definitely say that he manga gave out more emotions (if the mades sense lol). But anyways I still really like this drama a lot, it was cute and had two hot guys lol oh and I gotta say I cried a lot in this drama.
