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."
Forget producing more 
oxytocin than yesterday,
،انسَ أمر إفراز أوكسيتوسين أكثر من البارحة
Schmink dir lieber ab,
dass euer Oxytocin höher steigt als gestern.
No solo no están secretando
más oxitocina que ayer,
No solo no estás secretando
más oxitocina que ayer,
Au lieu d’augmenter
vos résultats d’hier,
Scordati di produrre più ossitocina di ieri,
Não está nem perto de produzir
mais oxitocina do que ontem.
Можешь и не мечтать
о повышении уровня окситоцина.
