Tooru and Sanae reunite at the book signing

Tooru and Sanae reunite at the book signing when Tooru unexpectedly finds his estranged sister, now writing as Keiko Nishikawa, at a crowded launch for her Akutagawa Prize–nominated novel. What begins as a stunned recognition becomes a reckoning with the years Sanae spent caring for their family and the life she left to pursue writing; Tooru’s refusal to call her departure abandonment allows them to meet again as brother and sister, while Sanae in turn comes to understand the devotion shaping his relationship with Maori Hino.

The unexpected encounter

On his way to meet Maori and Izumi Wataya, Tooru arrives early at the downtown terminal-station mall with a picnic basket. He takes the elevator to the thirteenth floor to visit a bookstore and finds the corridor packed with people holding books. A poster explains the crowd: a launch and signing with Keiko Nishikawa, an Akutagawa Prize–nominated author. The discovery stops him in his tracks.

Tooru pushes through the crowd, still carrying the bulky basket, until he reaches the signing table. There he recognizes Nishikawa as Sanae, his sister. She is seated at a long table, smiling as she signs books and thanks readers. The smile is unfamiliar to him: it belongs to a public moment in the life she has built beyond the apartment complex where he last knew her.

Sanae looks up, recognizes him, and says his name. Tooru tries to smile, but cannot manage it. The next reader approaches for an autograph, yet Sanae keeps looking at her brother, while the woman beside her is left unsure what is happening. Sanae returns to signing, whispers to her companion, and sends the woman over to greet Tooru as Nishikawa’s little brother. The formal event continues around them, but the recognition has already interrupted its orderly rhythm.

The distance behind the reunion

Their separation carries the weight of a family history in which Sanae took on adult responsibilities while still a child. After their mother died of heart disease, Sanae, then in her first year of junior high, managed the housework and cared for Tooru, who had just started first grade, while their father struggled with grief. Her domestic labor left little room for rest; reading novels after finishing the chores was her principal pleasure. The family home also held her father’s old books, and books became places she could visit through reading.

Sanae eventually left the familiar apartment complex to pursue writing. Her progress was rapid: about six months later, a novel by Keiko Nishikawa won the Literary World New Author Prize, and a year and a half after her departure another book was nominated for the Akutagawa Prize. At the signing, she describes the price of her ambition in terms of what she believes she sacrificed, including her family and Tooru. Her self-mockery gives the reunion an ache that professional success alone cannot resolve: the achievement is real, but so is her sense of having left her younger brother behind.

Recognition becomes conversation

When they speak more fully, Sanae apologizes for making Tooru wait and for cancelling his plans with a girl. He tells her he chose to accept her invitation because he wanted to talk, then asks about her book. She explains that the nomination on its cover sent sales soaring, prompting a rush first edition and a large signing crowd, but insists that writing matters more than the prize itself. She intends to make her living as an author and knows that winning an award does not guarantee a successful next book.

Tooru answers the deeper fear beneath her apology: he does not feel abandoned. He tells her she had been unable to do what she wanted for a long time, that he is glad she finally pursued it, and that he means his congratulations. Sanae, who had been looking down in shame, raises her head and smiles calmly. She says she had planned to contact him after the prize announcement, whether she won or not, a promise that makes clear the signing is not the end of their renewed contact.

Tooru’s care for Maori

Tooru also tells Sanae about Maori, explaining that she has anterograde amnesia: when she sleeps and her brain processes the day’s memories, those memories are erased. Sanae pauses, taking in the seriousness of the condition, then asks whether he truly likes Maori. His answer connects love to a practical intention: he wants to make each day happy for her, enjoy life together, and fill her daily journal with enjoyable experiences so that reading it will make her feel more hopeful.

Sanae responds with warmth rather than dismissing the relationship or the illness. The exchange gives her a new view of her younger brother: the boy she once cared for has become someone who is deliberately trying to make another person’s tomorrows easier to face. The promise recalls the family history of care, but its direction has changed. Tooru is no longer simply the younger child receiving Sanae’s labor; he is choosing how to care for Maori while respecting the life they share.

Renewed ties and wider significance

The encounter continues beyond the signing. Sanae exchanges phone numbers with Tooru and expresses regret for having left their father entirely in his hands. She offers to be contacted if Tooru has trouble with him. Tooru assures her that she need not worry about the family and that this is an important time for her; Sanae tells him he has become someone to lean on. Their exchange does not erase the history of separation, but it replaces the assumption that her departure ended her responsibilities with an invitation to stay connected.

The reunion is a reciprocal recognition rather than a simple return to the past. Tooru sees Sanae not only as the sister who once carried the household burden but as an author who has made a life through her work. Sanae sees him not only as the child she left behind but as a thoughtful young man sustaining Maori through the daily realities of memory loss. Their conversation turns success, guilt, and care into matters they can speak about openly, allowing affection to resume without requiring Sanae to abandon her ambition or Tooru to deny the pain of their years apart.
