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."
I'm half joking! Chris, you're the 
coolest person in the whole world.
.أنا أمزح! كريس، أنت أروع شخص في العالم بأكمله
Das war zur Hälfte Spaß. Chris,
du bist der coolste Kerl auf der ganzen Welt.
Lo decía un poco en broma.
Eres el chico más genial del mundo.
Lo decía un poco en broma.
Eres el chico más guay del mundo.
Allons, je plaisantais.
Non ero del tutto seria!
Chris, sei la persona più figa di tutto il mondo.
É meio brincadeira.
Você é o cara mais bacana do mundo.
Я же не совсем серьёзно!
Крис, ты самый-самый классный на свете.
