For the 2 fics you're looking for:
1. Polarity by @darkestcorners
2. I don't remember it being yandere and the reader wasn't a scientist, but more of an illegal tech person that can upgrades androids. I think the author mentioned about being inspired by Cyberpunk and the settings of the fic is futuristic. I don't remember if the fic completed, but I do remember the plot. Jk is an android of sort that wants to have free will/human emotions. He visit mc's place and pays a lot of money because her services aren't cheap and she's the top tech person in the black market (or something like that). Sadly, the author deactivate, if my memories serves me right, it was written by @jeonluvz.
Unfortunately for the first story, it's not Polarity since I did save that fanfic. I believe the fic only has 2 chapters so far and I remember saving the fic, just can't remember the title and I feel like the author might have deactivated which is why I can't find the fic since I can't read the contents.
2. Yes! I remember the author was updating everyday and then they just suddenly stopped. I remember saving the story, but don't remember the title.
Thank you for the help though!
