If you are looking for a romantic comedy then look elsewhere. This drama should not be watched if you are looking for a heart pounding plot. but i promise you if you love watching flawed like characters grow, if you love touching music, if you are bored with the stock dramas in dramaland and want to try something new and if you are ready to be shocked episode after episode then this drama is for you. This drama is not for the fainthearted or for the casual viewer. It took me whole of 17 episodes for me to decide if i love this drama or i hate it with a vengeance. This one lies somewhere in the middle. None of the 4 protagonists are your stereotypical characters from dramaland. All of them are flawed and selfish enough to self destruct themselves and everything around them. Eric Mun as Kang Tae Joo is forever etched in my mind as the bastard with the human heart. Don't expect to love him but he is the type of man who we love to hate. Eric did a fantastic job portraying his character and brought such range of emotions that i am shocked that this drama is so under appreciated and received low ratings in its time. I stand conflicted if i love the heroine or not. She is something for sure. She is the most unique heroine you will meet in dramaland. She looks naive and stupid but you will get to know her slowly and understand the things that she does. If you get past that horrible hairstyle that Jung Yoo Mi portrays throughout then you will see that her acting is pretty darn good. Their is quite a good chemistry between Tae Joo and Eun Soo. When I saw them together on screen i felt everything what they were feeling. Those simple touches, those hugs, those kisses. The chemistry is well done and their is no tight lipped kissing here. The Romance has a mature tone so no fluffy stuff here. Lee Kyu Han continues to get supporting roles but this man seriously needs his own drama to bring out the acting that i know he is capable of. He is quite good as Shin Joon Hyuk and as the man who is utterly cold and lonely in his life. Cha Hye Rin is the type of woman who is easy to understand and someone who is just as lonely as anything or anyone. The protagonists live in the hell of their own making and that is why this drama is full of so much angst. Their is lot of crying and moping and emotions flying around but it is not driven by external factors. This drama shows that we as humans are selfish and base. It is twisted and dark but oh so lovely to watch. It is told with raw realism and something akin to as if the writer can read our mind. Some shots, some quotes will forever remain in my memories. This was an intense drama that slowed down and kept on picking itself up at the same time. Don't expect a plot here.There is a plot though and it is quite good but not much happens in the way we viewers are used to. All the 17 episodes were about these 4 lives and their entangling and their character growth. The music is downright phenomenal from Gotan Project to "Moonrise" this is too intense a drama to be rewatched again. Give this one a chance..this starts a little slow but will be up and running in no time. Que Sera Sera will bring you a little closer to understanding the human nature and much closer to life's realities as well. But as Peter Bishop says "behind every cynic their is a romantic".
