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.
If that was all, then how could you 
have produced so much oxytocin?!
إن كان هذا كل شيء فكيف تمكنتما من إفراز 
!ذاك القدر من الأوكسيتوسين؟
Wie konnten sie nur allein damit
so viel Oxytocin ausschütten?
¡¿Cómo pueden secretar tanta oxitocina 
solo con tener la cabeza en su falda?!
¡¿Cómo pueden secretar tanta oxitocina
con un hecho tan sencillo?!
Poser sa tête sur ses genoux
lui suffit à en sécréter autant ?
Se hai fatto solo quello, com'è possibile
che abbiate prodotto così tanta ossitocina?!
Como produziu tanta oxitocina
só deitando no colo?!
Если это всё, то как вы смогли
выделить столько окситоцина?!
