Kamuro Aya, Miyaji Mahoro, Hinakura Riko, and Yomine Miharu all chase a balloon only to end up in their lesson room.
Suddenly seeing the four gathered like that, CEO Masaki smiles a smile full of meaning and says that "It's all inevitable."
Meanwhile, Aya is taking care of a weakened little cat.
Judging from its surgery wounds, Mahoro deduces that it's not a stray cat, but a lost pet.
Thus begins the search for its owner, but having grown attached to the cat, Aya can't quite put her heart into the search
She didn't tell anyone and 
did it all by herself.
.لم تخبر أيّ شخص وقامت بذلك بمفردها
Ohne jemandem etwas zu sagen,
hat sie das auf sich genommen.
Se esforzó mucho sola,
sin decirle a nadie.
Se esforzó mucho sola,
sin decírselo a nadie.
Elle s’est débrouillée seule
Non l'ha detto a nessuno e ha fatto tutto da sola.
Ela não contou a ninguém,
e fez tudo isso sozinha.
Она никому не сказала 
и ухаживала за ней сама.
