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."
Losing then running is the 
greatest strength of the weak.
.الخسارة والهرب هي أعظم قوى الضعيف
Die größte Stärke der Schwächlinge
ist die Flucht nach der Niederlage.
¿Pierdes y te vas? Típico debilucho.
¿Pierdes y te vas? Típico de los cutres.
Tu abandonnes devant l’adversité,
un classique…
Perdere e poi scappare
è la più grande forza dei deboli.
Fugir por causa da derrota
é a força dos fracos.
Проиграть и сбежать — лучшая
стратегия слабаков.
