Everyone is in line to get a blood sample for a health check. The girl is excited to be in line, but she's scared of being injected with blood. She's also afraid of being bitten by a needle, so she decides to stay away from the line. The nurse uses her blood vessels to prick her arm, but the nurse doesn't seem to be able to get the needle out of her arm. She slaps the nurse in the hallway, and the girl is relieved to see that the nurse isn't able to hurt her. She asks the nurse why she suddenly came back, and she learns that it's because the nurse felt the blood vessel wasn't hurt. She wonders if the nurse is a skillful nurse, and wonders why the nurse didn't slap the nurse earlier. Finally, the girl feels relieved again, and realizes that her hand is fine.
