So this is my first time writing a review and rating a drama while I am still in the second episode of it because I am the type of person who judges a drama by its ending but I just couldn't stop myself from doing so, I am just scared that by the end of the show I would think less of it, or maybe not enjoy the ending that it would not make sense to me, so i took the risk of rating it ahead of that. I have watched several Korean shows enough to know a good drama from a bad one, and this my friends maybe the most unique drama due to the actors performance. I have been transported and emotionally indulged in the second episode that it felt like i was the one playing the piano and taking all the music in rather than just watching it, that outstanding performance the delivery of the emotions is just WOW!! Yoo ah in is the perfect choice and I cant imagine an actor in his place because this role was written for him and only him! I will continue watching this and maybe update the review as well as the rating by the end of the show, so far I am forcing myself not to watch it all at ones but to take it 1 or 2 episodes at a time so that I would enjoy every bits and pieces of it and absorb the brilliance of each episode. UPDATE: I finished this drama in awe in how perfect everything fell into place, i liked the ending very much and i liked how true love can change a person to be better, and that is all what matters being better. And the fact that money and power dont matter but a peace of mind and a place or someone to call home. and God that music? its breath taking, how it magnifies the emotions of each scene and makes it memorable is all i can say!! Lee Nam Yun did a wonderful job in composing it (Four hands) is my fav of it. I highly recommend this drama.
