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.
This might be the last time, 
so I wanted to do it again.
.قد تكون هده هي آخر مرة، لذا أردت فعلها مجددا
Da dies das letzte Mal gewesen sein könnte,
wollte ich es noch mal erleben.
Como quizás sea la última vez,
quise hacerlo de nuevo.
Como quizás sea la última vez,
quise hacerlo de nuevo.
Je tenais à vivre ces instants heureux
une dernière fois.
Questa potrebbe essere l'ultima volta,
per cui volevo farlo di nuovo.
Pode ser a última vez,
então queria repetir.
Возможно, этим всё закончится,
и я захотела повторить эксперименты.
