Back at school, the art teacher asks nan to draw a picture of himself from his childhood. nan says he doesn't have pictures of his childhood because he's been away from school for so long. The teacher asks how long nan and chao have known each other, and nan tells the story of how they were neighbors when they were younger, but then their families moved away, so they didn't see each other again until after they graduated from middle school. Now, nan's grandma brings chao to her house for dinner every night, and he does his homework and plays games after his parents come home from work. He's a good kid, but now he looks stupid. .
