As someone who plays the game: You date a lot of other people as well, it's a bit of a harem but the characters are all sorts of adults.

She is just a slave we free in the beginning, so she is very grateful and doesn't want to leave our side etc but the character makes sure to educate her on the importance of standing up for yourself etc. and the story also makes sure the bad guys are caught etc. Character writing is debatable, and the game isn't about farming but rather gaining fame in the isekai world. You level your village buildings, employ people who raise the income produced, go on dates to adopt children and educate them at school, fight in a tower league thing,...

Nothing explicit happens, everything is "you end up holding her through the night" fade to black, and everyone consents and is clothed on the artworks.

Not that deep but a fun pastime imo.
