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...
I've never once held Yukimura-kun 
and fallen asleep with him...
لم يسبق لي أن حضنت يوكيمورا-كن
 ...أونمت بين ذراعيه
Ich bin nie mit Yukimura eingeschlafen,
während wir uns im Arm hielten …
Nunca he dormido abrazada de Yukimura.
Nunca he dormido abrazada a Yukimura.
Moi, je n’ai jamais pris Yukimura
dans mes bras !
Non ho mai abbracciato Yukimura-kun 
per poi addormentarmi con lui...
Eu nunca dormi abraçada
com o Yukimura-kun...
А я ведь ещё ни разу не засыпала, 
обнимая Юкимуру...
