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."
Little things making you happy...
...الأمور الصغيرة التي تشعرك بالسعادة
Schon Kleinigkeiten freuen einen
Te alegras y enojas por pequeñeces
y fantaseas con el otro.
Te alegras y enfadas por tonterías
y fantaseas con el otro.
Piccole cose ti rendono felice...
Pequenas coisas me deixavam feliz...
Любые мелочи тебя радуют...
