Does Myne in Bookworm ever gets better?

Hey, I'm at Vol 4 part 5, and I feel like Myne didn't really change much at all as a character, yes her circumstances changed (from commoner to noble) but it doesn't feel like she has grown or become any wiser.

When I first started reading I thought the direction of Myne's character growth would go along the line of "Oh! I see, so there's so much more to life than just reading books!", or something like that. But it seems to me that at this point of the story she still pretty much only cares about books and libraries. Responsibilities as a noble? nope. Trying to make the lives of her family that she supposedly cares so much about better? only secondary. Using that metric ton of mana that she got as a resource to grew more powerful so others won't push her around? No thoughts, only books.

Does she ever change? Is this how she's going to be till the end of the story? I wanna know if I should keep reading and expect something more.
