When Himuro finds out that her junior in the Ikeda lab, Kosuke, has spent over 220 thousand yen on his beloved Aika and holds her every night when he goes to sleep, she is shaken by the realization that the only present she's ever given Yukimura is a notebook, and that she's never held him while she slept. She worries that she can't objectively call what she feels "love." As Yukimura and Himuro endlessly debate "love" using numbers, Kanade proposes that the two of them go on a date, but...
Now, I can once again live by 
love as I have always done!
!الآن يمكنني ان أعيش بالحبّ تمامًا كما فعلت في السابق
Nun kann ich weiter wie bisher
unbesorgt meine Liebe leben!
¡Puedo volver a vivir por amor
igual que siempre!
¡Puedo volver a vivir por amor
igual que siempre!
Je reste le même,
je ne vis que pour l’amour !
Ora posso di nuovo vivere d'amore
come ho sempre fatto!
Agora eu posso viver pelo amor,
como sempre fiz!
Теперь я вновь смогу жить любовью, 
как и прежде!
