At the Okinawa training camp, Yukimura and Himuro shared a kiss of the highest theoretical value on a bridge of the greatest mood value under the beautiful, painterly rays of the morning sun. But the amount of saliva they collected was insufficient and so retesting is required. They head to the biological sciences' Regulation of Biological Systems Department to meet with a specialist in saliva testing. There, they find an alluring woman dressed like a traditional courtesan wearing a lab coat, Suiu, and her sweetheart, Chris. When Yukimura asks Suiu and Chris to help with their experiment to "give proof of love," Chris and Suiu flaunt their overwhelming aura of love.
When you dress nicely, it makes you feel 
more positive about things, right?
عندما ترتدين ملابس أنيقة فهذا يجعلك أكثر إيجابية، صحيح؟
Wer sich schick kleidet, empfindet
ein positiveres Lebensgefühl, nicht wahr?
Cuando van arregladas, 
son más positivas, ¿no?
Cuando las mujeres os arregláis,
sois más positivas, ¿no?
On se sent toujours de bonne humeur
quand on se met sur son 31, non ?
Quando ti vesti bene, sei più positivo
nei confronti del mondo, no?
Quando a gente se produz mais,
não nos sentimos mais confiantes?
Когда вы красиво одеты, то и чувствуете
себя гораздо лучше, так ведь?
