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.

At this rate, I won't be able to face

encarar meu salvador.
Я не смогу посмотреть в глаза 
тому, кто мне помог.
