As Tsukasa waits for Nasa to return home, a young girl named Chitose, who calls her "Nee-sama" confronts her. Chitose asks for Tsukasa to come home with her, and after being ignored, encounters Nasa. He tries to cheer her up, but after learning that Nasa is the one married to Tsukasa, Chitose's attitude suddenly changes. As Nasa tries to explain, Chitose shoves him into a black car that then drives away.
But there has to be some spot 
he hasn't cleaned already.
.لكن لا بدّ أن تكون هناك بقعة لم ينظّفها بعد
Ach, es gibt bestimmt noch Stellen,
die er noch nicht geputzt hat.
Il y a forcément des endroits
qu’il n’a pas nettoyés !
Ma dev'esserci qualcosa che non ha già pulito.
Mas deve ter algum lugar
que faltou limpar!
Должно же здесь быть хоть одно
неприбранное место.
