An explanation on my points given and why I am so dreadfully disappointed with this drama. Story: This story was awful. There were so many plot holes and inconsistencies that any good points in the narrative and any episodes I enjoyed were completely killed by an ending that was incomplete and worse...an ending where the writers treated their audience as stupid. There is no greater crime a writer can commit. If you see the last two episodes you will understand with glaring clarity what I mean. Too many major things were left unsaid and left undone. Horrible story and a terrible thing to do to loyal watchers who will have wasted 16 hours of their life investing in nothing. Now, I know I sound harsh but the writers deserve it...and I am actually a fan of the Hong Sisters...But I give no quarter as I cannot judge this crap work based on other dramas I have thoroughly enjoyed. Skip this and watch The Greatest Love, Hong Gil Dong or My Girlfriend is a Gumiho. Acting: As harsh as I am on the sad and enraging outcome of the story, I cannot be harsh with the acting. I place no blame on the actors of this drama. Gong Yoo was wonderful playing Kyung Joon; a boy trapped in the body of a 30 year old. And I would go so far as to say that his younger counterpart, Shin Won Ho did a good job playing Kyung Joon as well. He was cute and charming and I even felt chemistry between him and Gil Da Ran at the beginning. I would have loved to have seen more of him...especially toward the end. I like Lee Min Jung. I have seen her in several dramas and some movies too. I think she is a talented actress and while her part was written to be a bit weepy, like Gong Yoo, I find fault with the writing, not her acting. Suzy was much improved and Bae Sung Hyun who played Choong Sik was totally winning and adorable. It is really a shame when a talented cast is wasted on crap writing. The music was forgettable. I don't remember one song and never did I find myself humming a tune or looking up the OST on YouTube. Which is a bad sign because I do that a lot when a drama has a good OST. (see Me Too Flower and Coffee Prince) Overall, I walked away from this drama feeling cheated; out of a resolution for the characters, out of what could have been a fun story if it were written better, out of a Gong Yoo comeback drama that actually did not WASTE his talents and finally out of 16 hours of time that I want back. I won't watch this again and I caution anyone who hasn't watched to even begin.
