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.
Just being with you, the way we have been,
،مجرد التواجد معك، مثلما كنا
Allein unsere gemeinsame Zeit
und wie wir uns ständig fragen:
Solo quiero seguir como hasta ahora,
Solo quiero seguir como hasta ahora,
Poursuivre mes recherches
avec toi,
Mi basta stare con te, 
come facciamo sempre,
Só de estar com você, como sempre foi,
Просто быть и работать рядом с тобой,
