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?
We're just stepsiblings who used
 to date once upon a time.
نحن الآن مجرّد إخوة غير شقيقين
.اعتادا عن يتواعدا في السّابق
Wir waren einfach nur Stiefgeschwister,
die mal zusammen waren.
Ahora somos hermanastros
que solían salir juntos.
Ahora somos hermanastros
que solían salir juntos.
On est juste devenus
des frères et sœurs avec un passé d’ex.
Siamo diventati semplicemente dei fratellastri
che in passato uscivano insieme.
Agora somos apenas meios-irmãos
que já namoraram no passado.
Теперь мы сводные брат и сестра,
которые когда-то встречались.
