Not gonna happen, friend, all the old bastards have already been demonstrated in the story to be reprehensible people, the best you could possibly get is a route where one pretends to care to worm their way into her pants, and then sabotages her to become dependent on them. A loving route would require going back and completely rewriting existing scenes and maybe even altering future plans. Plus, I don't think any of the current men other than David is supposed to be a "good" route, that's the whole point of the plot, other than maybe (and this is a big maybe) Chris has a change of heart when he realizes what's actually going on and has a redemption arc and actually helps the couple out from psycho-ex's scheme and Anna falls for him. But all the other assholes? No chance, unless David's dad suddenly becomes an on-screen character out of the blue.
This is just my opinion of course, but I would stake a fairly hefty wager on it. If you're into vanilla olds getting some sweet romantic ass I suggest you look in other places, if you try to pin your kink hopes here, you're most likely going to be disappointed. I've seen it all too often where people try to convince themselves a game will feed their niche kink in the future, and when it inevitably doesn't, they linger around, rage-posting and badmouthing the dev and game.
