Symptoms Misread

A Child Changes
Early signs
Ryo begins wetting the bed, vomiting, and waking with headaches. His parents disagree about whether his behavior is emotional or medical.
A missed opportunity
A pediatrician eventually identifies the possibility of a brain tumor. The delay deepens Rié’s later conviction that she should have recognized what was happening sooner.
Hope in a Diagnosis

The Promise of Recovery
A treatable possibility
Doctors diagnose a germinoma and describe a high survival rate with radiation and chemotherapy. Rié clings to the possibility of recovery.
A family disagreement
Her husband opposes a biopsy, believing the risk is unjustified. Rié cannot confidently argue through the uncertainty and accepts his decision.
Treatment and Decline

Suffering at the Bedside
A mother’s vigil
Rié quits work and stays beside Ryo as treatment brings vomiting, mouth pain, weight loss, and exhaustion.
Hope turns against her
She continues because she believes the word recovery. When the tumor grows instead, she sees the treatment as suffering she helped impose.
The True Diagnosis

No Cure
A changed prognosis
Doctors identify glioblastoma and explain that Ryo has less than a year to live. Further hospital treatment cannot reverse the disease.
Regret begins
Rié imagines the food, play, and tenderness that might have filled his remaining time. Her regret becomes a lasting part of her grief.
A Death No One Can Exchange

The Irreplaceable Loss
A child dies
Ryo dies after seven months of illness, leaving Rié unable to make sense of the death she could not take in his place.
A lifelong question
His loss later shapes her distinction between an exchangeable identity and an irreplaceable death. The memory remains central to her understanding of X’s disappearance.
