Aha. XD Harutoki is one of three series by NeoRomance, with the others being Angelique and La Corda d'Oro. I'll bop you over this way for an introduction to it that's rather better than I could do. (I'm not overly familiar with most of Harutoki, but I think if you imagine a similar bishounen-harem theme set in a more Westernized fantasy universe, you'll have about nailed the heart of it.)
