I think i get what you're trying to say. As a Bisexual Woman (who is leaning more into Women), sometimes i get it; the frustration when playing through games that stated 'romance for everyone' but turned out, as you play, it simply.. didn't give off that vibe. There are a lot of games that focused on the Male ROs instead of the Female despite their games have the 'romance-for-everybody' undertone . Like, you just found a good story and expect you can romance the women ROs based on your orientation, but the vibes doesn't sit well with you. I get it...
But i'm not saying this story is wrong or you're wrong for stating that, no. Everyone has their own taste regarding stories, and every Authors can write what they want to write. And besides, the title of this game is 'The King's Hound' and the Author put the first line with "You are the King's Spouse". Surely the plot and the romance will be mostly focused on The King and us as the spouse? :') At least for a facade?. And i want to point it out that even if you're not into The King, you can romance the rest, and the rest of the ROs can be set into the genders you wanted them to be to.
My suggestion for you is maybe try to search and try to play the games that really clicked well with you? :') There are a lot of games with gripping and immersive plot and good romance sequence as well as this if you give them a try.
And maybe try to give this one a chance and wait it out, since it's still a few starting chapters here and in-progress :).
