Kōsei performs Chopin`s Ballade No. 1 in G minor, Op. 23 at the competition while Kaori undergoes surgery. He reminisces about his past experiences and the lessons he learned from the numerous people who have been a part of his life. As he plays, he enters into a dream-like state, surrounded by color and light. He is surprised to see Kaori and her violin before him. Kōsei understands instantly that this means that the surgery was unsuccessful, but returns a smile at her and continues his performance as the vision of Kaori plays along with him. He begs her to stay with him, but she disappears with one last tearful smile. In reality, Kōsei completes his performance with tears running down his face, saying his final farewell to her. Later, at Kaori's funeral, her parents pass on her final letter to Kōsei. As Spring approaches, Kōsei reads the letter, which reveals that Kaori, like the other pianists, admired him as a child and was influenced to play the violin in order to someday have Kōsei play the piano with her. She was overjoyed that they were in the same middle school, but was unable to speak to him because of his closeness to Tsubaki and Watari. She explains that in April, she told a lie - that she was in love with Watari - in a bid to get close to Kōsei. Now knowing that Kaori loved him, Kōsei reaffirms his vow to never forget her, continuing to play the piano. Watari continues his dating habits, but reminisces sadly about Kaori. Tsubaki, knowing that Kōsei had lost another person he loved, declares a promise to never allow him to be alone. Kōsei smiles, prepared for a spring without Kaori.
