Kotoko is now living with the Irie family, but Naoki is cold as ever. Naoki's mother Noriko always wanted a daughter, so she is ecstatic. Noriko gives Kotoko a photo of Naoki as a young boy dressed in girl's clothes. Kotoko now has the upper hand because she holds Naoki's secret embarrassment of his transvestite past, so she plans to have him tutor her for the final examinations, in order to enter the list of top 100 scores.
I'm saying it's a waste of time to 
take on an impossible challenge!
¡Digo que es una pérdida de tiempo
el echarse encima ese reto imposible!
¡Digo que es una pérdida de 
tiempo intentar un reto imposible!
Ça veut dire que défier l’impossible
est une perte de temps.
Eu estou dizendo que é perda de
 tempo tentar fazer o impossível.
