At the company camp, the young men are wasted and wet. The hot spring and the hotter things inside make them feel like they're in a cave. One of the men, known as "boss," calls out to the other one, "saka," and asks if they can go for a swim. The two men agree to go back to the shore. The other man, known only as "Mr. . ,aka," asks where they've been. The young men reply that they went for a long swim, and that they'll be back soon.
