Yukimura and the others will be giving presentations at the summer study sessions. There's less than a month left until the training camp, but Kosuke still hasn't picked a research theme. Professor Ikeda suggests research into "an algorithm that could instantly find the True End in any dating game." On the other hand, Yukimura and Himuro are focused on the hormone which is released when a person is touched by someone they love - oxytocin. By investigating the amount present in a person's saliva, they think they might be able to determine if the person loves the one who touched them, and they decide to immediately put it to the test with some close contact...
It's most effective if the area 
of contact is broad, right?
ستكون أكثر فعاليّة إن كانت منطقة الاتّصال كبيرة، صحيح؟
Es wäre sicherlich effektiver, wenn die
Kontaktfläche möglichst groß ist, oder?
Es más efectivo
si es un área más amplia, ¿no?
Es más efectivo
si es una zona más amplia, ¿no?
On réussira mieux
avec une large surface de contact.
È più efficace se l'area di contatto è ampia, vero?
Quanto maior a área de contato,
mais eficaz deve ser a produção, certo?
Чем больше площадь соприкосновения, 
тем эффективнее.
