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.
I like the way you always say things to me 
like "I love you" or "you're beautiful."
تعجبني الطريقة التي تقول بها أمورا 
"مثل "أحبك" أو "أنت جميلة
Mir gefällt, wie du mir immer deine Liebe
gestehst und mir Komplimente machst.
Me gusta como siempre me dices 
que soy hermosa y que me amas.
Me encanta que me digas lo guapa
que soy y que me quieres.
j’aime la façon que tu as de dire
Mi piace il fatto che mi dici sempre cose
come "Ti amo" o "Sei bellissima".
Eu gosto que você sempre fala
o que sente por mim e que sou linda.
Мне нравится, как ты всегда говоришь мне,
что любишь меня и что я красивая.
