While rushing to school in the morning, Akane and Isuzu come across some kittens abandoned on the road. That's where the two first met, unable to keep the kittens themselves and not wanting to leave them there they took the kittens to school with them.
Sorry for keeping you up so late.
Entschuldige, dass wir dich
so lange wachhalten.
Siento haberte tenido 
despierta hasta tan tarde.
Désolée, on est restées tard…
Scusaci di averti fatta stare
in piedi fino a quest'ora.
Desculpa por te fazer 
ficar acordada até tarde.
