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.
I wonder if something will 
inevitably end up changing.
.أتساءل إن كان أمر ما سيتغير في النهاية
Ob sich dadurch etwas
unwiederbringlich ändern wird?
¿Algo sí cambiará después de todo?
¿Al final cambiará algo?
J’ai peur que les choses changent.
Chissà se è inevitabile che qualcosa cambi.
Será que alguma coisa
vai acabar mudando?
Наверное, что-то в них
неизбежно изменится.
