Ep 21. Snow

Kousei finds himself in a state of distress after resurfacing memories of his deceased mother lead him to believe he won't be able to play the piano forever. He questions whether all the pain and suffering his mother put him through was worth it if he's going to lose the ability to play his beloved instrument at some point. Meanwhile, Kaori's health is deteriorating, and it's clear that her time is running out. Despite this, she remains determined to perform in their upcoming competition and urges Kousei to join her on stage.

In an attempt to bring some joy into Kaori's life, Kousei offers to teach her how to play his favorite Christmas song, "My Favorite Things." As they practice together, their bond deepens, and they begin to understand each other on a much deeper level. Kousei realizes that, while it's true that he may not be able to play the piano forever, the memories and experiences he's gained through playing are something that can never be taken away from him.

As the competition draws near, tensions begin to rise between Kousei and his friends, who believe that Kaori's determination to perform is putting her health in danger. Despite their concerns, Kaori remains steadfast in her decision, and Kousei agrees to join her on stage. The night of the competition arrives, and Kousei and Kaori dazzle the audience with their performance, which is filled with passion, emotion, and heart.

As they finish their final notes, Kousei is overcome with a sense of fulfillment and joy, knowing that he and Kaori were able to share this moment together. However, their happiness is short-lived when Kaori suddenly collapses on stage. Kousei rushes to her side, and as she takes her last breath, he realizes that she was the reason he was able to overcome his fear of playing the piano and inspired him to pursue his dreams.

In the midst of his grief, Kousei comes to a realization that music is not just about technical ability, but rather about the emotions and messages that it conveys. He finds comfort in the fact that, through his music, he can continue to convey his feelings and emotions to others, just as Kaori did for him.
