If you are hesitating to see this old drama, I beg you to give it a try. I honestly have no words to express how amazing it is. I guess not in vain it surpassed the barrier of 40 rating points. Story: The story is simply stunning, exceptionally well written, well-constructed characters with very human and powerful conflicts. It's different from other kdramas because, although there is a forbidden romance, what is really striking is how it shows the strength of family ties through many souls who can't find happiness because they are tormented by the past (and here, the past is represented by the piano). To recapitulate. An incompetent former mobster, who has just found out that he has a son, marries a single mother. A few years later when the woman dies in an accident, the stepchildren hate as much the stepfather as one of them ignores him and the other is given to low life almost like revenge. Thus in this story no one is willing to forgive: the stepchildren don't forgive the stepfather, the stepfather not forgive himself and the stepfather's son can't forgive himself for loving his stepsister. The only one who seems to be happy is the last daughter, who while filled with light the family, at the same time turns out to be the guilty to make the lovers' romance impossible. Acting: Absolutely outstanding performances. If I had never seen this drama, I would never have known that Korea also has its Al Pacino and it's called Jo Jae Hyeon. I take my hat off to his talent. On the other hand, I had never seen any work of Jo In Sung, but surely if you see this drama you will never see him in the same way. Most of the time he is covered with wounds and blood, hating his life and his stepfather. His performance is just extraordinary. OST: I started watching this show because I listened "Spring days of my life" by CAN, one of the most memorable songs in Korea. In the videoclip they showed scenes of the drama and so I decided to see it. Apart from this popular song, the OST is really very original. To end. This drama is full of homesickness and teaches us that we never reach happiness without forgiveness. The stepson never understand the love and good intentions of his clumsy stepfather until he discovers how much he can love a child that is not his. Beautiful reflection and sample of how life turns on a dime. Deep message that leaves you thinking how ironic we are as human beings. Furthermore, most likely you'll end up with a fervent desire to learn to play piano. 1000% recommended!
