Didn't they frustrate the 
hell out of you, Onii-chan?
Haben sie dich nicht
auch wütend gemacht?
¿No te frustraban, hermano?
¿No te fastidió, hermano?
Ça ne te fait rien
qu’elles disent des choses pareilles ?
Non ti sei sentito demoralizzato, onii-chan?
Você não ficou frustrado, Onii-chan?!
Тебе разве не обидно, брат?!
