When I first heard about this drama I was a bit skeptical as to whether or not I would enjoy it, but that was before I even knew anything about it. All I remember was seeing some crazy guys dressed in running suits. I finally got around to watching it and I can honestly say that it is now in my top 3 favorite dramas. I was incredibly impressed with the story and how they chose to end it because it was something you could accept. There were perhaps two or three episodes, mostly in the beginning and middle, that seemed to drag on a bit and I found myself skipping through some parts. But they weren't so major that it took away from my overall interest in the drama. I finished it in about three days and I'm glad I gave it a chance. I can't even begin to tell you how much I love the music! I love love love how the songs just perfectly match the mood the drama is trying to portray. True tears were shed for this drama, perhaps even sobbing and ugly sounds were made towards the end. The acting was great in my opinion. While there were a few times where I felt like Han Ji Min laughed a little too hard for it to be believable, it was easy to overlook and it didn't happen too often or so much to take away from the drama. The little prince sidekicks were awesome and I just fell in love with the trio. I'm not one to re-watch dramas and I can't say that I plan to re-watch this for awhile, but I definitely think it's on that list of dramas that if you were the type to go back re-watch your favorites, it would be towards the top of that list. I recommend watching this drama because it was touching and hilarious without being overly embarrassing or completely depressing which some dramas seem to have trouble finding the balance between.
