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 bought it because I really wanted 
double-eyelids, but ended up never using it.
اشتريتُه لأنّني أردتُ حقّاً إبراز جفني
لكن انتهى الحال بعدم استعمالي له
Ich wollte mal unbedingt welche,
aber hab sie nie benutzt.
La compré por capricho,
pero no la usé mucho.
La compré por capricho,
pero no la he usado mucho.
J’en ai acheté, mais en fait,
je m’en sers pas.
L'avevo comprato perché volevo la doppia palpebra,
ma poi non l'ho mai usato.
Comprei só por comprar e nunca a usei.
Купила зачем-то,
но так и не воспользовалась.
