Then... don't play it yet?? I've been following this for years but I know it's ambitious so I put it on a wishlist so I don't burn out of the available content.
You'll not find many otome games "suitable" for anyone under 16, and I say that as someone who played them since I was 9. Tell your kid to go play outside or read at the library where it's the librarian's job to keep your kid reading and reading safely.
