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.
I must warn her not to let a boy
lure her into his home so easily!
عليّ تحذيرها ألاّ تسمح لفتى 
!باستدراجها لمنزله بسهولة
Ich muss sie davor warnen, sich so leicht
in ein Jungenzimmer locken zu lassen.
Debo advertirle que
no se deje engatusar tan fácilmente.
Debo advertirle de que
no se deje engatusar tan fácilmente.
Je vais lui dire de ne pas suivre
naïvement un homme chez lui.
Devo avvisarla di non farsi portare
a casa di un ragazzo con tanta facilità!
Preciso avisá-la para não deixar um menino
atraí-la para sua casa tão facilmente!
Нужно дать ей понять, что нельзя
вот так наивно ходить к парням домой!
