One hot summer day, the 4 girls and Haruko are playing in the pool. They notice that Pets is missing. Kana later hears from her classmate Aida that Pet's family is very rich and they are moving to Mars. 
Sorry for keeping quiet about leaving
and saying those mean things.
Es tut mir wirklich leid.
Lo siento.
Lo siento.
Je suis vraiment navrée.
Desculpa não ter falado nada de ir
embora, e ter sido má com você.
Извини, что не рассказывала тебе,
да ещё и наговорила всяких грубостей.
