With Keiya unable to act while Mikio has a knife at Isaku's throat, it looks like both Keiya and Isaku are at Mikio's mercy. But when Mikio attempts to sexually assault Isaku, she doesn't play the role he scripted for her.
The measure done,
I'll watch her place of stand
تمّ القياس، سأراقب مكان وقوفها
Nach diesem Lied will ich zu ihr gehen
Cuando pare la orquesta estaré
al tanto del asiento que toma
Tras el baile he de observar
dónde se queda y tocar su mano
J’aimerais me rendre auprès d’elle
et lui prendre la main
"Finito questo ballo, osserverò 
dove s'andrà a posare e, toccando la sua,
Quando esta música acabar,
vou-me até ela.
Я к ней пробьюсь и посмотрю в упор.
