The discovery of parasites after the Singapore crab meals is the decisive break in a young couple’s four-day holiday: after repeatedly eating crab together, the man finds tiny worms on the crabmeat he has brought up and realizes that his girlfriend, who ate the same food, may also have swallowed them. He does not wake her. Instead, he sits through the night, convinced that something has changed beyond repair, and carries home a lasting refusal to eat crab.

The holiday and its routine

The episode follows a couple’s carefully protected vacation in Singapore. The woman is twenty-six and teaches English at a private girls’ junior high; the man is twenty-eight and works as an auditor at a large bank. Their schedules have made it nearly miraculous for them to take time off together, and they have chosen a place where they can be left alone. Each day they swim and sunbathe at the beach, stroll through town, and return in the evening to a small restaurant on a back street for crab. Their meals become part of a larger rhythm of pleasure and privacy, followed by time together at the hotel and restful sleep.

On their fourth and final day, they eat crab as usual. While picking the meat from the legs with metal utensils, they talk about how the beach, the daily meals, and the holiday have made life back in Tokyo seem unreal and remote. Their conversation remains with the present; silences come and go without disturbing the calm of the meal. The apparent ease of this shared routine makes what follows more isolating: the same food that has been a pleasure for both becomes a private crisis for the man.

The discovery

After returning to the hotel, the couple spend the night together and fall asleep. A short time later, the man wakes feeling ill and goes to the bathroom. In the dim light, he initially interprets what he has vomited as a large quantity of crab, reasoning that eating it day after day has simply made him sick. When the lump appears to move, he first doubts his eyes; after switching on the bathroom light, he sees that its surface is covered with countless tiny worms, almost indistinguishable in color from the crabmeat.

The sight intensifies his distress. He flushes the toilet repeatedly, washes his face, and looks at himself in the mirror, feeling estranged from his own appearance. The discovery is not presented as a confirmed medical diagnosis: what the man sees is the worms on the expelled crabmeat. But he immediately connects that evidence to the meal he and his girlfriend have shared. When he returns to the bedroom, she is still asleep, unaware of what has happened and of what he fears may now be inside her.

The decision not to wake her

Watching his girlfriend sleep, the man considers whether he should wake her and tell her what he has seen. He decides against it. In his view, she has noticed nothing, and that fact becomes the central difficulty: the two people who shared the meal now occupy sharply different versions of the night. He faces the discovery alone, while the ordinary scene around him—the sleeping woman and the undisturbed room—continues as if nothing has changed.

He remains awake in a chair by the window, trying to regulate his breathing and wishing he could sleep until the crisis had somehow passed. Instead, he becomes certain that their relationship has altered. He plans to return to Tokyo the following day, but doubts he will ever again feel toward his girlfriend as he did before the discovery. His sense of rupture extends beyond the relationship: he also doubts that he will be able to get along with himself. The episode’s force lies not in a demonstrated outcome for either person’s health, but in the irreversible change he believes has occurred within his understanding of their shared life.

Aftermath and significance

The man spends the remainder of the night sitting quietly until dawn. His girlfriend does not wake, and the holiday’s earlier scenes—the restaurant, their conversations, and the shared meals—return to him as events that now seem distant. By morning, he feels that he no longer knows where his life is headed. Yet one decision is definite: wherever he goes, he will never eat crab again.

The meal’s transformation from shared pleasure into private alarm gives the event its central contrast. The couple had sought a temporary refuge from their ordinary lives, and their repeated dinners helped make that refuge feel self-contained. The discovery breaks that sense of separateness: an unseen consequence may have followed them into the room, but only one of them knows about it. The story leaves the girlfriend’s condition unconfirmed and their future unstated, ending instead on the man’s changed perception and his refusal of the food that had organized the holiday.
