It's Kousei's turn to take the stage, and everyone is waiting to see whether or not he will be able to play. How will he be able to perform with the memories of his mother still floating in his mind?

Kousei's concerns for Kaori temporarily subside as he runs into her on the street and they go shopping. Nagi can't take the harsh criticism she receives with Kousei as her piano teacher.

Knowing her time is limited, Kaori undergoes a risky operation, hoping to have the chance to play with Kousei on stage one more time.
