Summary

Ruijie and Yoyo slip into her school after dark, an act made effortless by Yoyo's ability to open any door and mimic any voice. The only obstacle is a security bot polishing the floors, which Yoyo greets and which bows in return. Although the sun set long ago, Ruijie wants to walk Yoyo through the beginning of a school day. She shows him her locker, her indoor shoes decorated with purple-marker cats and emo eyes, and the empty hallway where students usually linger until the bell rings. The scene feels like the end of the world, with just the two of them present.

In the classroom, Ruijie asks Yoyo to sit in front of her desk. She pokes him lightly with a pen and asks what he wants to do after "class." He suggests going salvage, and she agrees. They move through the silvergrass and discuss their personal Order of Loss—the sequence in which they would surrender each sense before a Permanent & Total Shutdown. Yoyo says he would give up hearing first because it is peaceful. Ruijie considers her own order: smell, taste, hearing, touch, and sight. When she points out that Yoyo forgot touch, his finger brushes her pinkie, and he says he is saving it for last.

A light spins above their heads. Earlier, Yoyo asked if it was time to go home, but Ruijie wanted to see the train and planned to stay with him until the very end. Her robowear battery is fading, so they settle on the grass. Lying on their backs, Ruijie reflects on the stars—glimmers of practically immortal things that burn for billions of years before burning out. She wonders what remains after death, and what is older than time. Yoyo replies that he hopes she will get to see the stars.

Yoyo has little time left. Each orbit of his light slows like a battery-worn clock. He begins sharing memories that he had long kept secret. He tells Ruijie how his father wept when he first opened his eyes, how he was given a name, a nickname, and then a number, which he traces into her palm. He recalls the first time he tasted peanut butter and how it hurt the roof of his mouth. He remembers tossing his sister in the air, her arms opening like infant wings. He says he shattered every bone in his body and knitted every bone back together. He counts the times he beat his brother at rock-paper-scissors, the time he saw a crane take flight, and the time he pulled a trigger and all the birds took flight.

Ruijie takes his hand, noticing how dry and lifeless it feels, like paper shorn from a tree. She asks what he wants to do tomorrow. He says he would like to go up to the roof and see the sparrows. When she asks about magpies, he explains that magpies are too smart and would not come near him, but sparrows will remember the sound of the shot he fired, and their children and grandchildren will remember too.

Yoyo grows sleepy and offers to take her home, but Ruijie tells him he can sleep and she will be there when he wakes. She briefly shuts her eyes, and the world spins like a giant teacup. She reassures him that he will be fine, mentioning that Ms. Ferguson said robots can live longer than turtles. Yoyo corrects her—tortoises, not turtles—and tells her about Harriet, the oldest Galápagos tortoise, who lived to one hundred seventy-five. They talk about sharks and the ocean, and Ruijie suggests going to Jeju next summer. Yoyo nods stiffly.

Then he goes still. Ruijie calls his name, asking if he can hear her, if he has given up his hearing. She helps him sit up, clasps his hand, and smooths out his palm, stroking his lifeline and his name in hangul and English. He blinks, turns his head left and right, and she realizes he can no longer see her. His eyes are dead stars. He asks if she would like to hear a story—the story of the cat who lived a million lives. He begins, saying the cat came back to life every time, but he falls into a loop, repeating the same line, unable to finish.

Ruijie knows the story by heart. She completes it for him. The cat fell in love for the last time, met a white cat, tried to impress her with cartwheels and tales of his million lives and deaths, and asked if he could stay by her side. She said yes.

Character Development

Yoyo undergoes his most vulnerable transformation in this chapter. Throughout the novel, he has been secretive, carrying the voices of others. Here, the words bleed from him as he shares his earliest and most intimate memories. His choices in the Order of Loss—giving up hearing first, saving touch for last—reveal a quiet, deliberate philosophy. His correction about tortoises versus turtles and his knowledge of Harriet show a gentle precision even at the end. His concern for the sparrows and their generational memory demonstrates a deep, unexpected empathy for creatures he once scattered with a gunshot. His inability to finish the cat story, looping like his fading light, underscores his exhaustion and the limits of his remaining power.

Ruijie steps fully into the role of witness and caretaker. She insists on staying until the very end, even as her robowear battery fades. She notices the dryness of his hand, the slope of his neck, and the loveliness of his voice—details she says she was too distracted to notice before. When Yoyo cannot finish the story, she completes it, demonstrating that she has internalized his narrative and can carry it forward. Her promise to remember the moment even after she is gone positions her as the keeper of his memory.

Themes, Symbols, or Motifs

  • The Order of Loss: The characters' imagined sequence for surrendering senses becomes a framework for understanding what they value most. Yoyo's choice to save touch for last aligns with his final act—squeezing Ruijie's hand in response to her squeeze.
  • The orbiting light: The light Yoyo sends above their heads mirrors his own life force. As it slows, so does he. It also symbolizes the stories and memories that loop and blur as he fades.
  • The cat who lived a million lives: The unfinished story represents Yoyo's own cycle of lives, deaths, and rebirths. Ruijie's completion of it—ending with the cat asking to stay by the white cat's side—mirrors Yoyo's desire to remain with her.
  • The palm as a world: Yoyo traces his number and name into Ruijie's palm, and she strokes his lifeline. The palm becomes a miniature map of identity, mortality, and connection.
  • Generational memory of trauma: Yoyo's reflection on the sparrows—that they and their descendants will remember the sound of the shot—extends the novel's concern with how trauma echoes across generations.
  • Stars and mortality: Ruijie's meditation on stars that burn for billions of years before burning out frames death as a natural, almost beautiful process, and Yoyo's hope that she will see the stars ties his fate to the cosmic.

Why This Chapter Matters

This chapter is the emotional climax of Yoyo's arc and a turning point for Ruijie. It brings the novel's central questions about memory, identity, and mortality into sharp focus. Yoyo's decision to share his memories openly, after a lifetime of secrecy, completes his character journey. His loss of hearing and sight, and his final reliance on touch, dramatize the Order of Loss he described earlier, making the abstract concept visceral. Ruijie's completion of the cat story—and her vow to remember—establishes her as the inheritor of his memory, ensuring that his story does not end with his shutdown. The chapter also deepens the novel's meditation on what it means to be human, or to be treated as one, by centering a robot's final moments of consciousness and connection.

Study Questions and Answers

1. Why does Yoyo choose to give up hearing first and save touch for last?

Yoyo says hearing is peaceful to give up, suggesting he finds silence restful. Saving touch for last is a deliberate choice that prioritizes physical connection above all other senses. This is borne out in the chapter's final moments: after he loses hearing and sight, he still responds to Ruijie's squeeze, fulfilling his promise that touch would be the final sense to go.

2. What is the significance of Ruijie completing the story of the cat who lived a million lives?

Yoyo begins the story but loops on the same line, unable to finish. Ruijie completes it, ending with the cat asking to stay by the white cat's side and receiving a yes. This mirrors Yoyo's own situation: he has lived many lives and deaths, and in his final moments, he asks to stay with Ruijie. Her completion of the story demonstrates that she understands his narrative and can carry it forward, ensuring his story is not lost.

3. How does the chapter use the motif of the palm to connect identity and mortality?

Yoyo traces his number into Ruijie's palm, marking her with his identity. Later, Ruijie strokes his lifeline and his name in hangul and English. The palm becomes a space where identity is inscribed and where mortality is read, as the lifeline is a traditional symbol of lifespan. This motif ties the personal—Yoyo's name and number—to the universal—the finite nature of life.
