It all started when Kang Jae-hyuk happened to watch the child prodigy, Lee Hajin, perform on TV. From that moment onwards, Jae-hyuk couldn’t get the beautiful sound of that violin out of his mind. Later on, Jae-hyuk didn’t hesitate when his HJ Cultural Foundation group got the chance to sponsor the precocious Hajin. Hajin would later confess his love for Jae-hyuk but it turns out, that confession was also a farewell as he would leave the cultural foundation for good. Years have passed and Jae-hyuk has decided to drop by Hajin’s new violin performance. But…has his playing always sounded this pained? What happened to the once beautiful music that came out of Hajin?
