Wakana felt relieved just for a moment after they got all of the materials they needed for Marin's cosplay, but then he's shocked to find out that he needs to finish the cosplay in two weeks. On top of that, his grandfather, Kaoru, hurts his back, so Wakana has to run the shop and he also has midterms. Wakana feels overwhelmed and gets depressed, wondering if he'll ever actually become a kashirashi at this point.
I-I'm also sorry for carrying on 
this project without telling you.
أ-أنا آسف أيضاً للعمل على هذا
المشروع دون أن أخبركِ
M-Mir tut es auch leid, dass ich einfach
weitergemacht und nichts gesagt habe.
Yo también siento haber
trabajado en ello sin decirte nada.

Je m’excuse d’avoir avancé
sans t’en avoir parlé.
D-Dispiace anche a me di aver portato avanti
il progetto senza parlartene.
Peço desculpas por não
ter falado nada a você.
И ты меня. Зря я, конечно,
всё делал втихомолку.
