A added brother (Harry potter)

I am a new writer, so my writing a skills might not be as good as others, but I will try my best to improve as I go, this fic is going to have a heavy amount of world building and slice of life, so don't get mad at the slow pace it will have.

I don't want to spoil anything for you so this will be short, but I hope you injoy it.

a man from our world comes to a tragic and accidental ending, but those who caused said accident want to push it under the rug, our dashing good looking MC, from luck of the spin gets a new chance at life through reincarnation to the world of Harry potter, and it's magical wonders.

how will this new person change the story we all know. will it be for good, or will it be for bad, who knows, because I certainly don't, but if you wish to see a magical world threw me, follow me to a new world unseen.
