I don't particularly care who you put him with as long as it is a singular person. I have read your other HP stories, and while they were extremely well written and very enjoyable overall, I did not particularly enjoy what you did with his love life. Most harems ruin stories. you and enlion are part of the very (VERY) few that can write them well enough to not detract from your storytelling. Even though that is the case, I would still prefer a singular partner. That's just my opinion, though. I find it distasteful to dictate what authors should write, so I will not tell you what to write, but I hope I have made my opinion on the matter of Harry's love life clear.
It's your story, so do what you feel comfortable with writing in regards to the pairing mate. Imo though, Hermione to me always seemed a better fit as a sister figure, even if I do like the way you're portraying her. Still, she's rather dependent on Harry and I can't see them in a truly equal relationship atm. Fleur or in a few years even Tonks would fit better I think. Fleur could be the passion to his logic, and Tonks pushing him into properly enjoying life with her goofiness/impulsiveness(tempered by auror training), whereas Hermione is perhaps too much like him as things stand now. Harry and Hermione dating for a few months to a school year could see them figuring out that they're much too alike, with Hermione honestly having little to over Harry doesn't already bring to the table himself. With Fleur going to work for Gringotts as a warder or curse breaker(not sure which it canonically is tbh), she could be a liaison to the Goblins as well if he wants to rent out grants to them to help with vault security and such? Honestly Fleur's Veela nature is also something you can really play with, especially with a System like Harry's. Giving himself Creature abilities perhaps, upgrading Fleur's heritage with some Phoenix genes for further control of her allure and regeneration maybe? Honestly you're a creative writer and despite it's flaws and rather shallow harem romance I really did like Origin(and the one before) so I'm sure wherever you choose to go with this fic it'll at least be fun to read.
