Tbf liaden doesn't actually do anything she's just at the counter while azyrrans stalking her from the back saying "that ass is free real estate". I dunno, since she doesn't seem to be pursuing anyone else whatsoever, it seems like they should just restructure it into a throuple. "I love you, but I love her too, and want to be with both of you and love you both equally." Haven't played a female or futa but I assume that'd be the easiest one to show that with more inclusion in content, but male or female wise they could add in more dedicated azz PC liaden quests or interactions, group dates etc, tweak the liaden centric stuff for you both caring for her since she wasn't the one to get the sword and all but not feeling like a third wheel, just empathy not guilt trip, it's close to being that currently but there's something about it that feels icky and wrong but I'm not smart enough to single out the specific wording and reactions.
Honestly easiest thing would be to make liaden bi but that'd probably be a political minefield. Just tweak the dawnsword quest so the PC and her get isolated and grow closer, or naturally do, then it becomes all 3 love each other no matter the gender combo instead of the current system.
Heck a third alternative is to keep liaden les, but male characters can still have 3some smut scenes by not messing with liaden and just tag teaming azyrran. Boink az while az is boinking liaden similar to the Berwyn(may he rip) cait random scene, or how brienne is in threesomes. Not interested in the other person but enjoys you having a bonus.
At the end of the day all the az stuff isn't a huge deal, but it's something that really needs to be handled early because eventually brints supposed to go after his own harem, just like az was, and supposedly wsans making the PC "his favorite" but it'd be nice to just have characters on either side of the harem as "families" instead of favorite systems. A bunch of husbands and/or wives instead of side bish 1-7 basically imo. From a smut game perspective it'd come across a lot better too if you liked the person and the people in the harem so you'd lessen ntr type feelings and strengthen all the characters at the same time. Making the PC have the favorite spot just creates the opposite effect of what liaden currently is imo.
