A couple visiting Singapore is walking along the beach when they come across a cute restaurant that the woman insists on eating at. Becoming enamored with the food, which advertises various crab dishes, they return multiple days in a row. On their third day back, and their final day before returning to Tokyo, the man rises in the middle of the night and vomits in the toilet. Flicking on the lights, he finds hundreds of tiny, crab-colored worms crawling on his bile. Sick to his stomach, he vows to never eat crab again. As he reflects on the trip overall, he makes the decision to break up with his girlfriend because their relationship has been irrevocably changed by this event.
