I think the setting works quite well for examining a feeling of directionless. Scandinavia despite is highly individualistic with people respecting personal autonomy. You are supposed to succeed and contribute, but these demands aren't expressed by family members directly telling you to have kids or become an engineer. Your critique that people aren't directly demanding that she changes, settles down, or finds a job, is pretty par for the course here. But the pressure doesn't come from people demanding that you change but rather everyone else changing while she doesn't feel ready. Saying that you could just "walk away" misses the point of the story which is that you cannot "walk away" from growing up, from aging, from the limitations that life brings.
