The Kanda Used Book Festival happens over the course of a week in October. Takako and Tomo attend, and Takako makes sure they run into Takano while they peruse the stores. Takano joins them and the trio have a great time finding used books across the neighborhood.

At one point, they run into Sabu, who shops with his wife. His wife laments that Sabu owns too many books, and Sabu panics when she suggests he get rid of some. Takako, Tomo, and Takano spend the entire day together, and at dinner that night, Takako is impressed with Takano’s knowledge of foreign literature.

After Takako and Satoru close up their shop on the final night of the festival, they have their own little post-festival party in Takako’s room. Satoru tells Takako that she can stay there forever if she wants. When she asks why he is so kind to her, he tells her that he loves her and that she saved his life. 

Satoru explains that when he was younger, he was depressed and felt lost in the world. When he was at his lowest point, Takako was born, and when Satoru met her, he felt a joy that inspired him to find himself.
