Rachel isn't one of the "originals".
The original characters were the group of girls in the mansion. Rachel didn't come in until the script went all generic incest plot after a few updates.
Plot went to shit for some reason.
Started off great. MC moves into mansion, set to take over from his uncle to work on the project of a lifetime IF the MC lives in the mansion. The girls were there to serve him and deal with his sexual appitites. All that was part of the will.
Then the plot changed and he went home to momma which technically should have voided the will but who gives a shit about continuity and plots making sense.
So, we had the usual son lusting over mother and added in a hot aunt too. Then we get another plot with the aunt losing her luxury lifestyle and taking a job where she's being tasked to seduce her nephew.
Then we got a really hot scene where the mother helped the MC fuck her employee ....... then the dev decided we can't have nice things, took the hotness out of it and made it dull.
Meanwhile we have a plotline going on where MC is starting a relationship with one of his girls.
We also have a mother/daughter duo of lawyers that suck at their job and suck the MC.
Then we get one of his older girls going for revenge on her ex and helping MC bang his new girlfriend in yet another new plot thread to boost her life.
So this super important work that was the driving point of the story at the start is no longer super important because incest.
All in all, a game that started off super good then the dev had a massive brain fart and decided his game needed 30 plotlines that didn't fit together while forgetting the original plot and it's storylines in one of the most schizophrenic, all over the place jumbled messes i've ever witnessed in a game.
"So why play it" I hear no one ask ..... because i'm hoping it gets back on track and the dev puts down the bong and stops eating magic mushroom stroganoff.
He is radically changing the content of the game.
