As punishment for the underwear incident, Mizuto demands Yume go on a date with him. Yume is taken aback by the sudden development, but little did she know that it was all part of Kawanami Kogure's devious plan, a plan to shatter Minami Akatsuki's delusional dreams of marrying Mizuto only to become Yume's doting little sister. And how else to do it but to show her that Yume only has eyes for Mizuto?
Tonight is the night I capture my 
little brother's shining moment.
اللّيلة هي اللّيلة الّتي سألتقط فيها
.لحظة أخي الصّغير المتألّقة
Ich werde nun meinen fein
angezogenen Bruder verewigen.
Hoy voy a retratar
el punto álgido de mi hermanito.
Hoy disfrutaré
del punto álgido de mi hermanito.
C’est l’heure de ta séance photo,
petit frère.
Stasera immortalerò
il momento di gloria del mio fratellino.
Esta noite é a noite em que capturo o
momento brilhante do meu irmãozinho.
Сегодня я запечатлею
минуту славы своего брата!
