First thing that I have to say it's I had a lot of expectations about this drama, and all of it was destroyed in a million pieces before halfway, I forced myself to end up clinging to just a few characters.

Do Hoon was my favorite, and I believe his performance was good. His development was smooth, he could had something more and that made me very frustrated. From the beginning, you could see that it would have relevance in the protagonist's life, so i confess i hoped they would get closer and develop some romance and a happy ending for him. But that didn't happen, too bad.

My second favorite was Ran Joon, I just started watching because of her. I really love Ahn Heeyeon. And this character had a fun development, smooth and good. She had the best happy ending in this drama and it was fun watching her scenes.

And I admit that I liked the main character a little. Ji Won was cute and adorable character, but her love story with Seung Yoo didn't make me feel anything. He was a character that I didn't like from the beginning, it bothered me the way it was written and I didn't feel any empathy. He was boring. The character I liked least.
Seung Yoo It could have had a great performance, a great development, but his script was a little annoying. As if he didn't have a personality or something that made us want to see more, him cheating on his girlfriend with his first love and screwing it up is not the biggest problem. The thing that I hated was his personality, his character construction.

I have to say that the entire construction of the script was a little disappointing. I would definitely not watch it again. The scenes were not very well fitted and it was extremely tiring to watch. This was a drama that left nothing no feeling. totally forgettable.

I wouldn't even recommend it.
