Yukimura is working hard on his computer, as usual, when Himuro suddenly says, "I am in love with you. Her confession greatly shakes Yukimura. Unlike the last time, Himuro states her feelings matter-of-factly. Yukimura asks, "What theory did you use to determine that you love me?" Himuro replies by taking Yukimura out on a date and begins performing experiments they've done before such as measuring heart rates, using an emotion counter, collecting saliva, and the kiss experiment.
then turning those feelings into an equation
فتحويل تلك المشاعر إلى معادلة
dann schreibt man diese Gefühle
in eine Gleichung
que convierta sus sentimientos
en fórmulas, les asigne valores
que convierta sus sentimientos
en fórmulas, les asigne valores
mon seul recours
est de m’en remettre à la science.
allora tanto vale trasformare 
i sentimenti in un'equazione
valorar os sentimentos numa equação
