Though Yukimura and Himuro went as far as to kiss for the experiment, they were soundly beaten by Chris and Suiu's oxytocin levels in their saliva. Panicked, Yukimura suggests that they conduct control experiments. However, in the midst of the Yukimura/Suiu pairing, Suiu's seductive manner ends up causing Yukimura to ogle her charms. Seeing that, Himuro runs another experiment with Yukimura, but ends up sulking. The two end up having a lover's quarrel. Yukimura's behavior causes Chris to look down at him coldly and say, "As a man, you are a failure."
In spite of the fact that she had 
been hostile shortly before,
،بالرغم من أنها كانت عدائية قبل قليل
Obwohl sie ihm bis gerade noch böse war,
Aunque estaba molesta con él hasta hace
un momento, lo defendió enérgicamente.
Aunque estaba enfadada con él hasta hace
un momento, lo ha defendido con pasión.
Alors que vous veniez
de vous quereller,
Nonostante fino a poco prima fosse ostile con lui,
Embora ela estivesse tão hostil
alguns minutos atrás,
Хоть она и злилась сейчас на Юкимуру,
