Well cassanova? Well as much as I can tell not all the girls are interested in him, Weiss rejected him in the first 2 seasons but that might change after season 5,Ruby what I seen she and Jaune have mostly friends, Nora is just a team mate and she's more interested in Ren, Blake she spent more time with Sun all she with Jaune that their voice actors use to date, as for OP I seen that more from Ruby while Jaune is still an Underdog, as fandom giving Jaune really don't see it as being that bad since I do it myself and I seen worst from the fandom,
