Seems antinatural, as most VNs are aimed towards a specific audience (either men or women), and feature routes to please that audience.
Also to have actual romance your protag should be bi, and that's too much for now (unless it's OELVN), otherwise you have the bad endings where you wind up with your pal, or the joke routes that are pretty much the same.
Another one, deIz by Mike Einel, you have a best pal ending (among a big variety), but I recall it was a "resignation" ending in which you play videogames with him and all that, because you missed any and all significant relationships.
