why am i obsessed with a children's book

I am so torn over The Cursed Child. Half of me desperately wants to love it, and be excited for the book. I want to preorder it and obsess over more story by J.K. Rowling.

The problem is, I feel like I can’t accept it. And it’s not part of the original canon, so I have the liberty to reject it as reality. Here’s why I don’t like it:
It doesn’t make sense to me for Harry.

Through the entire establishment of Harry’s character “an overworked employee of the Ministry of Magic, a husband and father of three school-age children” just doesn’t make sense.

The Harry I know was forced into a war as a child. He was forced to fight make choices that cost lives, would he really choose Auror as a career? I dont think so.

The Harry I know lived for his time at Hogwarts. He worshipped Remus Lupin, the best teacher he ever had. In his fifth year, he became a teacher to his peers. He was great at it, and he loved it. Are you telling me he wouldn’t have chosen to become Professor Potter instead of going back to the war he was forced to fight? I dont think so.

I don’t see it, and I can’t see it. Harry ought to be happy, he ought to have chosen a career that makes sense for the development of his character. As a teacher he could live up to what Remus was to him, he could right the wrong of how Snape treated his students. He could be the teacher he wanted when he was at Hogwarts, and he could make Hogwarts a home for others as it was for him.

Hogwarts is where Harry Potter belongs.
