A young pianist Jinwoo Yoon who's slowly losing life into their musical career, spots someone in a crowd. Who weirdly enough a complete stranger's gaze gives him the confidence to atleast make this concert impress him. After the concert he thinks about the eyes of the stranger, afterall Jinwoo's personal belief is that the eyes are the window to the soul. Jinwoo isnt exactly famous but he's not unknown, articles are spiraling about who jinwoo looked at. Can Jinwoo track down this stranger? Even if so, what is that weird feeling from that man?
