Takaki is now a computer programmer in Tokyo, and Akari is preparing to get married. There is no indication as to what Kanae has done. Takaki is still longing for Akari to the detriment of his lifestyle and his other relationships, which a recent ex-girlfriend also acknowledges. Akari, while going through some old things, finds the letter she intended to give to Takaki but never sent. She feels nostalgic for those days but has moved on with her life. On the verge of a breakdown, Takaki quits his job.

One day while walking down a road, Akari and Takaki presumably pass and recognize each other, across a train crossing. They both pause and begin to look back, but the passing trains quickly cut off their view. Takaki waits for the trains to pass, but sees that the woman is gone. After a pause, he smiles to himself and continues walking.
