No, I was thinking of Utawarerumono. Calling it harem might be stretching it, considerung true, full-on harem anime, but I still remember it to be annoying how the catgirl, the angel girl and other girls, too, were clinging around the main character ... Hakuoru his name, I think. Itīs just a dumb concept, especially if youīre unsuccessful with women yourself irl :P
