I like how you are straight up about Romance in your story but is their a list of females in the harem that you will post? Also I like that you're trying something hard like a gaming fanfiction but be careful sometime it easy to forget little details in your own story. I can't wait to see what Harry going to do in this world. Remember try changing how canon went beside adding new characters in the story it will make people want to read your story more instead of following canon word by word and scene by scene. (That would get boring real quick!) This a good start but I can't wait to see how you improve upon it.

Good Luck!
