(
Dropped at chapter 2.)
Weird hyper-virgin fantasy.... Why does this story have to be an isekai?? Basically this is "How to (self-insert) cater to those who can't even imagine to speak to a woman 101".
The whole medieval isekai + slavery aspect of the story is there to force the MC, the FMC, and they
adoptive daughter into a family.
You can't get a GF, and/or you can't imagine to get a relationship?
You can't imagine to get married?
You can't imagine to knock up your GF/wife?
You can't imagine that your own child would be an adorable kid?
You can't imagine that you would be able to maintain a family on Earth?
Then this a story is for you.
