Aragorn should be a baby or maybe not even born during the Fall of Smaug. So there shouldn't be a beloved for Arwen, yet.

Tbh your novel looks like an adaptation from Chinese translation at the first look but if you dig a little deeper and make some searches you will find out it's an original work with heavy inspiration from multiple entertainment type novels. I quite enjoy reading it.

I am a bit confused, is he a reincarnated person or this HP universe contains I Cast as a muggle fiction.

Dropped too much senseless drama . The entire robbery arc was stupid Even the 2K era had a bunch of security measures yet somehow on 40K he thought the whole Warehouse was unsecured. I thought maybe the author could pull the story together somehow but it's getting worse.

While the story is above average, writing needs heavy editing.

I was expecting pure swordsmanship maybe a one piece level psychical strength with training.
