Summary

When Ji-won arrives home in the late afternoon, she finds her sister Ji-hyun alone in their cramped shared room, pacing in the two or three steps of open floor space between the bed and the desk. Ji-hyun's anxiety is unmistakable, and she immediately asks whether Ji-won has noticed anything strange about their mother lately. Ji-won has not. Ji-hyun explains that Umma has been making phone calls at night—not from her bedroom, but from the bathroom, with the fan running to muffle the sound. Ji-hyun suspects their mother is talking to a man.

Ji-won dismisses the idea, pointing out that their mother is still married. But Ji-hyun reveals she has found divorce papers: their father filed them as soon as he left, and the divorce will be finalized after a three-month waiting period. Ji-won is stunned. Neither sister has spoken about the possibility of divorce, and both had quietly assumed their parents' marriage would somehow repair itself. Ji-hyun notes that divorce is almost unthinkable in their culture—every unhappy couple their parents know stays together regardless.

Ji-hyun asks Ji-won to pay attention to their mother that evening. As the sisters sit together, Ji-won wonders whether Ji-hyun remembers a night in July when she asked if things would be okay—and whether Ji-hyun remembers that Ji-won lied.

At dinner, Ji-won sees that Ji-hyun is right. Umma is unusually cheerful, even glowing. She has regained weight she had lost after their father left, her cheeks are fuller, and her eyes are lively. Several times she excuses herself from the table and disappears into the bathroom. Through the whirring of the fan, the sisters hear quiet, muffled giggles.

Ji-hyun is alarmed. She insists they need to do something, arguing that it has only been a few months since their father left and that their mother is vulnerable and sad. She speculates wildly about the mystery man—a scammer, a predator, even a serial killer. Ji-won points out that their mother's strict schedule—working at a Korean grocery store from morning to evening, with no hobbies and few friends—makes it hard for her to meet anyone. Ji-won suggests the man could be someone from work, but Ji-hyun counters that nearly everyone at the store is female, except for Mr. Lee, the elderly manager, who is far too old to be a romantic interest.

When Umma returns to the table, her cheeks flushed, Ji-hyun confronts her directly, asking who she was talking to. Umma denies it, claiming she was using the toilet. Ji-hyun then blames Ji-won, saying her sister heard the conversation. Ji-won kicks Ji-hyun under the table, but Ji-hyun does not flinch. Umma nervously giggles and tells Ji-won she is imagining things, patting her shoulder. Ji-won glares at her sister, and Ji-hyun sticks out her tongue.

Back in their room, Ji-won chases Ji-hyun, pins her to the ground, and demands an apology. Ji-hyun fights back with her fists, but Ji-won is twice her size. Ji-won tickles her until she is screeching and crying. When Ji-won finally lets her go, Ji-hyun kicks at her head but misses. Furious, Ji-hyun storms off, declaring she will never speak to Ji-won again.

Character Development

Ji-won — This chapter deepens Ji-won's role as the family's quiet observer. She initially dismisses Ji-hyun's concerns, but the revelation of the divorce papers shakes her. Her internal reflection about lying to Ji-hyun in July reveals guilt and a protective instinct that she cannot fully act on. Her physical dominance over Ji-hyun—pinning her, tickling her until she cries—shows a pattern of using force to manage conflict rather than addressing it directly.

Ji-hyun — Ji-hyun emerges as the more emotionally attuned and anxious sister. Her childhood habit of scratching her ankles raw under stress, leaving a permanent scar, is revealed as a lifelong pattern. She is the one who discovers the divorce papers, who notices the secret phone calls, and who confronts their mother. Her wild speculation about the mystery man—scammer, serial killer—reveals both her protective instincts and her tendency toward catastrophic thinking.

Umma — Though the chapter is told from Ji-won's perspective, Umma's behavior is the central mystery. Her cheerfulness, regained weight, and flushed cheeks suggest a new romantic interest, but she actively conceals it, denying the phone calls and deflecting Ji-hyun's questions. Her nervous giggle and hurried denial show she is not ready to be honest with her daughters.

Themes, Symbols, or Motifs

Family Secrets and Deception — The chapter is built on layers of concealment: Umma hides her phone calls, the divorce papers are discovered rather than discussed, and Ji-won lied to Ji-hyun in July about things being okay. The bathroom, with its running fan, becomes a literal space of secrecy.

Cultural Stigma Around Divorce — Ji-hyun notes that divorce is almost unimaginable in their culture and that unhappy couples stay together. This context explains why Umma might hide both the divorce and a new relationship, and why the sisters assumed their parents would reconcile.

Surveillance and Suspicion — The sisters actively spy on their mother, straining to listen through the bathroom door. Ji-hyun's suspicion turns paranoid, imagining worst-case scenarios. The chapter shows how family members can become both protectors and investigators of one another.

Vulnerability and Anxiety — Ji-hyun's scarred ankle is a physical symbol of her lifelong anxiety. Her concern for their mother's vulnerability—worried she might be preyed upon—mirrors her own fragility.

Sibling Bonds Under Strain — The tickling fight is both playful and violent, ending with Ji-hyun's vow to never speak to Ji-won again. The sisters' closeness is tested by the stress of their parents' separation.

Why This Chapter Matters

Chapter 9 marks a turning point in the family's dynamic. The divorce, previously an unspoken possibility, becomes a concrete fact that the sisters must confront. Umma's secret romance introduces a new element of deception that will likely drive further conflict. The chapter also deepens the sisters' relationship, showing both their intimacy and their capacity for cruelty. Ji-won's guilt about lying to Ji-hyun in July foreshadows deeper consequences, and the chapter's ending—with Ji-hyun storming off—leaves their relationship in a fragile state.

Study Questions and Answers

1. Why does Ji-hyun react so strongly to the possibility of their mother having a new boyfriend?

Ji-hyun's reaction stems from multiple factors: her anxiety-prone personality (evidenced by her childhood stress-scratching), her protective instincts toward a mother she sees as vulnerable and sad, and her belief that it is too soon after their father left. Her catastrophic speculation—scammer, serial killer—reflects her tendency to imagine worst-case scenarios.

2. What does the bathroom fan symbolize in this chapter?

The bathroom fan represents concealment and the lengths Umma will go to hide her secret. By turning on the fan, she creates a barrier of noise that prevents her daughters from overhearing her conversations. The fan also symbolizes the broader pattern of deception in the family, where important truths are muffled and obscured.

3. How does Ji-won's lie in July affect the reader's understanding of this chapter?

Ji-won's internal reflection—wondering if Ji-hyun remembers that she lied when asked if things would be okay—reveals that Ji-won has been protecting her sister from the truth about their parents' marriage. This lie contextualizes Ji-won's initial dismissal of Ji-hyun's concerns and suggests she has been carrying guilt about not being honest. It also foreshadows that the family's problems are deeper than either sister has acknowledged.
