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?
Going home separately thus 
concludes our date at the aquarium.
إنّ الذّهاب للمنزل منفصلين
.يُنهي موعدنا إلى حديقة الأسماك
Wir gehen getrennt nach Hause
und damit ist das Aquarien-Date gelaufen.
Y nuestra cita en el acuario termina
yendo a casa por separado.
Y nuestra cita en el acuario termina
yendo a casa por separado.
Après être rentrés séparément,
notre rencard prendra fin.
E così si conclude il nostro appuntamento
all'acquario, mentre ci separiamo per tornare a casa.
Ao nos separarmos para voltar para casa,
nosso encontro no aquário termina.
Дойти до дома по отдельности —
вот конец нашего свидания.
