You did such an amazing job creating all the characters that honestly Harry isn’t Harry Styles to me in these books. In my brain, this Harry is a fictional character. I totally understand changing the name and will 100% still be reading no matter what you decide, but I definitely think you could only change the last name and keep Harry and it would just be as if it’s just his name if that makes sense. I’m not sure this made sense but, I don’t picture Harry Styles when I read the book, I picture a character that you created. so if you decide to change the name it won’t make too big of a difference in my vision of the character, but if you decide to not change it that’s also okay because again, I don’t even picture Harry Styles I picture devils due Harry.
Hope that made sense! Love your books can’t wait to read more <3333
