The Story

At Seoul Station's crush of commuters during a busy holiday weekend, the father moves ahead through the crowd the way he always has, expecting Park So-nyo to keep pace behind him without complaint, as she has for decades of marriage.

He boards the train ahead of her, as always, and looks back for her, so certain she is following — instead the platform is empty of her, the crowd has closed completely over the space where Park So-nyo stood, and the train pulls away without her.

Chi-hon and Hyong-chol are urgently summoned when the father confesses he lost Mom in the station crowd. Seoul is a maze she barely knows, and dread quickly displaces the family's first assumption that she simply wandered off nearby.

Hyong-chol and Chi-hon tally what Mom left with: no phone, almost no money, and only a shaky, uncertain ability to read street signs. Stranded and unable to ask for directions with any real confidence, she could be anywhere at all in the sprawling city.

But the family's account leaves room for something more than mere illiteracy or unfamiliarity with the city; whispers of failing health or worsening headaches around that day linger at the edges of what is told, though this detail stays genuinely uncertain rather than something the novel confirms outright.

Making a missing-person flyer, the family realizes with a jolt that they own no clear photo of her alone — only group shots where she stands at the edge. Someone recalls she wore mismatched sandals that morning, a small detail that suddenly feels deeply ominous.

Hyong-chol and Chi-hon print the flyers anyway and launch a citywide search, canvassing Seoul Station's platforms, nearby streets, and shelters, showing her description to strangers who barely glance up, chasing a woman none of them can fully describe.

Searching, Hyong-chol keeps circling back to memory: Mom scraping together money and years of labor so he could study, certain he would become someone extraordinary. He never quite became the man she imagined, a gap he has never spoken aloud.

That unspoken debt now drives him forward; Hyong-chol searches with a frantic, almost punishing energy, as if enough effort could still somehow repay her. Yet every lead he chases collapses into nothing, and the city gives him no reliable trace of her.

Alone with the search, the father revisits decades of walking ahead of her in every sense — absent, self-involved, letting her labor go unnoticed. Her disappearance forces him to see how completely he had assumed she would simply always be there.

His memory keeps snagging on one old wound: a long affair he carried on years earlier, a betrayal Park So-nyo endured in silence. Searching for her now, he cannot stop reliving how little he gave her in return for her loyalty.

He has always assumed there would be time to make it right, so the father never confessed or asked forgiveness outright. Now she is gone before any reconciliation is possible, leaving his guilt permanently unanswered and his apology forever undelivered.

Chi-hon remembers how Mom always seemed uneasy and evasive around books and letters, yet pushed her hardest toward reading and writing, even toward becoming a novelist herself. At the time Chi-hon read this only as ambition for her daughter, nothing stranger underneath it at all.

Chi-hon is Mom's daughter and a novelist, the most introspective and guilt-ridden of the family's narrators; much of the novel's opening section addresses her directly in the second person, as 'you,' so her own reckoning with Park So-nyo unfolds almost like an accusation she cannot escape.

Piecing together small moments over many visits — Mom asking others to read signs, mail, and restaurant menus aloud — Chi-hon slowly realizes the plain truth: her mother could barely read at all. What looked like preference or failing eyesight was, all along, near-illiteracy.

Chi-hon understands it was never carelessness but concealment: Mom hid her illiteracy for an entire lifetime, ashamed in front of the very children she raised to read freely. No one in the family had ever known, or thought to ask.

But Hyong-chol and Chi-hon are not the only children searching for her; additional sons and daughters take part in the search and the family's reckoning to varying degrees, at least one reportedly living abroad, though the novel gives Chi-hon's and Hyong-chol's perspectives the fullest weight among the siblings.

Comparing what they've each separately learned, Hyong-chol and Chi-hon realize they are uncovering a private Park So-nyo neither ever truly knew — a woman with her own shame, sacrifice, longing, and inner life, obscured for years by the single word Mom.

A stranger calls in a possible sighting: an elderly woman matching her description, seen wandering confused near the station days after she vanished. Hope surges through the whole family for the first time since the search began, sharp and almost unbearable.

The family rushes at once to follow it, but the woman is gone before anyone arrives, and the details blur under questioning. Like every lead before it, this sighting dissolves into ambiguity, unconfirmed, leaving them exactly where they started, only more exhausted.

Hyong-chol and Chi-hon start to dread the ringing phone as much as they crave it, since each near-answer only resets their hope only to break it again. The repeated cycle of almost-finding her becomes its own prolonged, exhausting form of suffering.

Among the fragments the long search turns up, one recurs: someone outside the marriage who seemed to understand and value a side of Park So-nyo her own family never nurtured, a private self she kept carefully apart from her role as wife and mother.

Neighbors and near-strangers describe quiet, unexpected acts of generosity — help given, kindness offered without asking — that none of her own children ever witnessed or even heard about. Each new story of the woman she was outside the house deepens the family's guilt.

The narrative shifts at last into Park So-nyo's own voice, fragmented and drifting, addressing people from her past as though they can still hear her. For the first time, the reader — not just the family — is let inside her.

In this voice, Park So-nyo becomes a daughter again, remembering her own mother with tenderness, and she revisits her marriage plainly, without her children's usual softening. She names, too, the lifelong private struggle to hide how little she could actually read.

A deeper grief surfaces here: Park So-nyo seems to quietly address a child lost long ago, in infancy, a private sorrow she carried silently through decades of raising the children who survived, never once naming it aloud to any of them.

Her section grows steadily more dreamlike and untethered from ordinary time, memories folding into one another as if spoken from somewhere beyond the physical world. It reads as though Park So-nyo may already be dead, though nothing confirms this outright.

Back in the present, the exhausting search that Hyong-chol, Chi-hon, and the father have driven for months finally stalls out entirely: no body is found, no rescue reported, no verified contact ever made. The physical hunt for Park So-nyo simply ends.

No body and no sighting of Park So-nyo is ever verified, despite every flyer, tip, and canvassed street. Her fate stays open and unresolved, neither confirmed dead nor found alive, and the novel offers no closing scene that settles the question either way.

Though Park So-nyo's own fate is never confirmed, Chi-hon survives the ordeal and carries its unresolved grief forward with her long afterward; therefore the novel's final scene does not return to the search at all, but instead follows Chi-hon alone, all the way to Rome.

Some time later, Chi-hon travels to Rome for a literary conference and stands quietly inside St. Peter's Basilica before Michelangelo's Pietà, the marble Mary cradling her dead grown son — a mother's grief carved permanently into stone, universal and unbearably specific at once.

Facing the sculpture, Chi-hon silently begs the Virgin Mary to look after Mom, since her own family could not. Hyong-chol and the father live on carrying that same failure, forever changed by a woman they only truly saw once she was gone.

What it means

Therefore this vanishing crystallizes an idea the novel returns to again and again: a mother's individual selfhood gets erased by her own family's lifelong habit of only ever seeing her as 'Mom,' so that until she disappears, no one in the household thinks to ask who Park So-nyo actually is underneath that single role.

Therefore a pattern crystallizes across every family member's account: love and understanding arrive only after the person is gone and can no longer receive them, so each fresh realization about who Park So-nyo truly was doubles as proof that it always comes retrospectively, always too late.

Park So-nyo's hallucinatory voice leans the reader toward believing she has died, yet the novel refuses to confirm it, insisting instead that not-knowing is its own grief — the book's real subject is how Chi-hon, Hyong-chol, and the father only see her fully once she is gone, too late for the presence they'd always assumed was permanent.
