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.
We have as yet only determined 
whether or not we love each other.
.لقد حدّدنا ما إن كنا نحب بعضنا أم لا فحسب
Bisher haben wir nur bestimmt,
ob wir einander lieben.
Acabamos de determinar que nos amamos.
Acabamos de concluir que nos queremos.
Nous savons juste
que nous nous aimons,
Per ora abbiamo solo determinato se ci amiamo o no.
Só determinamos se gostamos
ou não um do outro.
Мы лишь выяснили, что любим друг друга.
