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...
For those unpopular men and women 
who don't have someone to love,
بالنسبة للرجال والنساء غير المحبوبين
 ،ممّن لا يملكون شخصًا ليحّبهم
Wer keinen Kerl oder respektive Frau
zum Liebhaben abbekommen hat,
Para quienes no tienen a quién amar,
también sirve el contacto con mascotas.
Pero si no tienes a quien amar,
también sirve el contacto con mascotas.
Et pour ceux
qui n’ont pas trouvé l’amour,
Per le persone con scarsa popolarità 
e che non hanno nessuno da amare,
E se você é um fracursado
que não tem ninguém pra amar,
Для тех мужчин и женщин, 
кому некого любить,
