Aiko wears a turko dress.
A talent scout spots her talent and offer her to come to his show. Aiko was excited and talk to everyone in her class.
But she didn't know the same talent scout comes to Taeko before. Taeko's Father didn't want his daugther to perfom in a show, because it is just entertainment. Taeko's Mother telled Taeko not to talk about it at school. Otherwise she will hurt Aiko's feeling.
