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.
Because of him, my old self 
is rearing her ugly head again!
بسببه، ها هي ذي نفسي القديمة
!القبيحة تصعد للسّطح ثانية
Nur deshalb tritt mein altes Ich
wieder zum Vorschein!
Por su culpa, mi vieja
yo está peleando por salir.
Por su culpa mi vieja
yo está peleando por salir.
Il a réveillé
celle que j’étais autrefois !
La vecchia me è riemersa a causa sua!
Isso acabou despertando
aquela antiga eu!
Из-за него моё убогое прошлое
опять дало о себе знать!
