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.

Das war eine subjektive,
unbegründete Annahme, korrekt?
Fue algo que cada uno afirmó sentir.

È stata un'affermazione personale
e non dimostrata, no?
Foi uma afirmação pessoal, certo?
Это ведь личное недоказуемое суждение.
