When the scene opens, Cai tells her sister that she's afraid that the students at school will find out about her and her brother's activities at school. She's worried that they'll be able to figure out that she didn't want Cai to participate in the activity, and she'll think Cai's cat is mad at her for not letting him help her tie her shoelaces. Cai tries to explain that she doesn't need her brother to help her, but she can't help blushing when she thinks about how embarrassing it would be if Cai saw her like this in public. When Cai asks her mother why she has so much hair on her, her mother tells her that it's because she has too much cat hair, and that there must be lots of bacteria in her room. Cai asks if she can see a bruise on her leg, and her mother says that it was when Cai was participating in an activity. Cai tells his mother that she should be kind to Cai first, and then Cai will be okay.
