Only in death did I realize the meaning of my life.
Daehwa Kim is a piano prodigy who drops out of a prestigious performing arts high school due to a lack of passion. Just when he finally discovers his love for the piano at 30, he gets into a fatal accident, only to wake up as a high school student again! Can he turn his fate around this time?

I only realized that when I was on my deathbed.
My life barely had any meaning without the piano of mine.
But when my eyes opened again, there I was standing by the piano keyboard.
