Taken in that context, you will have to admit that it is nearly impossible for a brother and sister, who have lived together for almost the entirety of their lives, to form a romantic love in the way that would occur naturally between people who are not related. Haley and the MC were never going to go out on dates, call each other on the phone, gift each other flowers and chocolates, invite each other out to lunch, or any of the other things that come naturally to the courtship process. They didn't need to do those things, because they have lived closely together for so long that they can complete each others sentences... and even thoughts.
I still maintain that Haley loves, and has loved, the MC in any possible form that love can take (except by definition
philautia 
).
That is what I meant...I see it similar to Cercei and Jamie in GOT, except in this one it was one sided. Where with GOT it was mutual.
BTW, I do see this whole story as plausible and realistic. It's part of why I'm so invested in this.
I'm perfectly capable of using porn logic, and to be perfectly honest in most incest game, you have to use it.
I mean in Dating my Daughter...Not using porn logic, the dad is pretty bad. Like Klaus level bad (Ok not Klaus level, but pretty close) Even Dreaming of Dana, is better, but it's still pretty messed up. The beard options in that game is …..pretty damn rough.
Most incest games are just plain implausible. Like 1 line in the dialogue....and everything is back on. "Oh son, we can not do this, I'm you mother ", "Mom, if two people love each other it does not matter", "OK son, let's fuck. I wanted you since the day you were born"
You have to use porn logic to enjoy these games.
It's rare gems like Deluca Family, City of Broken Dreams etc Where you do not need to switch of your brain to enjoy the game, that I truly enjoy. For me Haley's story falls into this category. If there ever were an incest story between brother and sister, this is what I a imagine it could have gone like. So I judge it accordingly.
Make no mistake, I love games where you use porn logic. DMD, Big Brother, Sisterly Lust are some of my favorite games. They are just pure fantasy.
Haley does not fall in that category.
