Hmm, I see. I usually consider H content to be a bonus for visual novels, but I do still read those that don't have them. If you're looking for more conclusive romances, Clannad would be most up your alley. In comparison, Little Busters is more mystery oriented than it is romantic. Still has some good romance in routes like Haruka's and Kud's, but they can be a bit lacking in the others.
