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."
After many years together,
،بعد سنوات عديدة مع بعض
Nach vielen gemeinsamen Jahren
Descansar la cabeza en la falda
de tu novia de años
Descansar la cabeza en el regazo
de tu novia desde hace años
Ainsi, reposer sa tête
sur les genoux de son partenaire
Dopo molti anni insieme,
Após tantos anos juntos,
Спустя годы отношений
