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?
Did you leave your stock 
contemptuous laugh at home?
هل نسيت ضحكتك المليئة بالازدراء في المنزل؟
Wo hat er sein unerträgliches
Gespött gelassen?
¿Dejaste en casa tu ironía
y tu risita insoportable?
¿Te has dejado en casa
tu ironía y tu risilla insoportable?
Où est passée
son arrogance habituelle ?
Ha dimenticato a casa la sua solita risata sdegnosa?
Ele esqueceu em algum lugar aquele
estoque de risada de desprezo?!
Ты оставил привычный
надменный смех дома?
