Finally having found what she wants to make, Himeno does a 180 and dives headfirst into making pottery.
Meanwhile, Toushirou keeps worrying that his suggestion to Himeno is torturing her because her behavior is so different...
That made me get cocky and 
I ended up ruining it.
اغتررتُ بعد سماع ذلك
وأفسدته في نهاية المطاف
Was ich mir zu Kopf stiegen ließ …
Cuando me dijo eso, me confié,
Al decirme eso, me confié,
Ces paroles m’ont rendue
trop sûre de moi,
Ma sentendo quelle parole mi sono gasata troppo
Fiquei meio convencida com isso,
então acabei estragando tudo.
Я потом так собой
загордилась, что всё испортила.
