The general plot of the drama is just beyond explanation... IT'S AMAZING and definitely NEVER DONE BEFORE :D. As a drama watcher, I sometimes analyze scenes and body language of the characters in it. The characters in here had their own characteristics, but they would sometimes have a confusing stance in order to fully support the drama. This happens because of the time limit in each episode. Normal dramas would take 50-60 minutes per episode, though this drama only had 40-50 minutes. The rest of it is used for end-credits. It's sad because if the drama was given more time, it would be a memorable and amazing drama that could strike up to the top 10 drama rates.
Although some scenes felt "empty" as if something was missing, the drama itself has a unique and heartwarming storyline which I would recommended for those who have enjoyed dramas for a long time. Wouldn't necessarily recommend it to those who just started out dramas. Why? Just "cause" ;).
