I have had in mind for quite some time a story about a sexbot who starts off having no free will or agency, just pure programming. She is basically a super advanced toaster with tremendous acting skills who is programmed to behave like the ideal sex mate for her owner. But that's all it is: An act. She has zero emotions of her own, zero free will. It's all a pretense.
And then something happens after she meets her owner. A confluence of circumstance and happenstance. And she becomes sentient and sapient. And falls in love with her owner. At that point, although she is still compelled by her programming to be attracted to her owner and is compelled by her programming to want to have sex with her owner, she has free will and agency within those constraints.
I mention this for two reasons:
1) That's one possible way the author of this manga can avoid (or explore!) some thorny ethical issues about sapient sexbots.
2) If I ever get up off my ass and actually write the fiction I have in my head, I want it on record that I didn't get the idea from this manga. :D
So "Detroit become Human" with sex bot
