It's nighttime at the Irido residence. Yume has somehow found herself with Mizuto's boxers in her possession. If Mizuto were to find out, it would almost certainly mean she would have to face the punishment of admitting to being the younger sibling. Hoping to avoid this outcome, Yume waits for Mizuto to fall asleep before heading to the bathroom to return his underwear to the laundry basket. But who does she pass in the hallway, but a bewildered Mizuto, mouth agape, with Yume's very own bra dangling from his grasp.
You mean to say that stealing my underwear
 and keeping my things in a little box
تقصدين أنّ سرقة لباسي الدّاخليّ
والاحتفاظ بأغراضي في صندوق صغير
¿Robarme los calzoncillos
y guardar mis cosas en una cajita
¿Entonces robarme los calzoncillos
y guardar mis cosas en una cajita
Mi stai dicendo che rubare i miei boxer
e tenere le mie cose in una scatola
Então quer dizer que roubar minha cueca
e guardar minhas coisas em uma caixinha
То есть ты украла мои трусы
и держала мои вещи в шкатулке,
