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.
Why are you all so excited?
لمَ أنتم متحمسون هكذا؟
Wieso seid ihr so aufgedreht?
¿Por qué están tan contentos?
¿Por qué os alegráis tanto?
Arrêtez de dire n’importe quoi,
vous deux.
Perché siete tutti così su di giri?
Por que estão tão animados?
Чего это вы так переполошились?
