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 repeated a cult-like ritual 
of smiling creepily
كرّرتُ طقسًا يشبه الطّقوس الدّينيّة
من الابتسام بريبة
Und als würde ich damit
einer Gottheit huldigen, …
Era como un ritual,
sonreía como una idiota
Era como un ritual,
sonreía como una idiota
boîte que je vénérais
comme un être sacré,
La guardavo e sorridevo
in modo inquietante in una sorta di rito,
E repetia um ritual no qual
eu soltava um riso asqueroso
Словно одержимая,
я смотрела на неё с жуткой улыбкой,
