In a manga I found the following sentence:
What does the
なろうとなんだろうと means? The remaing part should mean something on the lines of "She must notice by himself [...] if she hurt herself", and the given translation is something like (I'm translating a translation, sorry for any inaccuracy) "Even if she will hurt himself, he must notice it by himself".
I found a couple of questions (here and here) in which part of that expressione appears, but they doesn't really seem to apply; a Google search wasn't helpful, either, and my grammars doesn't have that form, which maybe is a mix of multiple forms?
