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.
And as you walked this path of love,
،بينما تمشيان في طريق الحبّ هذا
Seit ihr den Pfad der Liebe beschreitet,
E, mentre percorrevate 
questo cammino dell'amore,
E conforme seguiam
em frente com esse amor,
Вы вместе шли дорогой любви,
