All I can say right now is Rowoon has won me over again!
Only at episode 4 while I am writing this quick review and it was so hilarious.
If your the type of watcher that likes to laugh and just enjoy a fun
filled drama, then start watching. The negative reviews are just
from so called watchers who think they could create a better story and
they can't. Bringing down a Drama at first 4 episodes when it's
so fun, only tells that these people are simple targeting greatly
made dramas to keep down the ratings on MDL. In fact it's already
greatly received.

Update after finishing this series-
This was beautifully made and loved how they did not reveal everything in
one go and also loved that the M & F leads had a lot of time for their relationship scenes.
The paste was steady flow, not rushed and the last 5 episodes were wrapped up nicely,
It's quite refreshing to how this story telling was done, most dramas always overload
the last episode but this one paste it and kept what they needed to until the last 2 episodes.
Very good all round cast and the scenes in the office with the co workers made me laughed
alot especially Mr Gong, he somewhat filled the show with his witty unserious character.
My score at the start was 10/10 and it remains the same.

The OSTs were so good especially "I'll Always Be With You" by lyn
