Human x Machine romance?

I'm looking for something like Willful Machines, where the main character falls in love with a human-seeming robot. Detroit: Become Human and the Terminator franchise also fit, haha. Is there anything like that?

Some things I'm looking for:

Main characters who're 18 to 25 years old.

Ideally a well-built setting.

Not purely romance, but with a strong plot line that incorporates romance into it, if that makes sense?

Anybody have any recs like that?
