I agree about LFA - it definitely does evidence some awareness of the problem, though not nearly as much as Paper Towns. Which I can't remember if you've read yet or not! If not you definitely should.

And yes - to me that's the best sort of the story. The kind that portrays the process honestly, because it's a human thing to do and it happens to us all, but also moves beyond it enough to make it clear the unknowable person being idealised is actually a human being.
