I love the actor Song Seung Hoon since I saw him years ago in Autumn in My Heart but in this drama, the character he portrayed seemed mediocre. Doesn't have much character build up and not much drama to express his acting.
At the beginning it was interesting to watch how the main leads meet and we look forward to what would happen next. But then out of the blue came the exes at the same time then it got annoying. But then the girl's ex-bf pretty much took over the show, or at least that's how I feel. He has some past that he couldn't talk about and somehow the characters in the show are connected to him. I feel like this character overshadowed the main lead and actually the actor portrayed his character real well that I just feel so sorry for him. Then like a lot of k-dramas, they speed things up towards the end just to wrap things up. It was well wrapped up, but just like dumplings, you can wrap it good, but the inside also matters. In this case, it was average at best.
