You were enslaved in a mine on the Planet Mongo and one of your female reptile overseers has taken a liking to you. Rebuff, accept, try to escape?

The protagonist wakes up in a suburban home to find they apparently have a wife, a child, and a dog, none of which they have memory of. As the so called family members reference warm familial memories they cannot recall, complete with photos of their vacation trips, the protagonist starts accepting that they might have amnesia or had an aneurysm... until they find a piece of paper in their pocket saying 'none of this is real'. Reality itself starts glitching in increasingly bizarre ways.

You're a cyberspook who's been trapped in a simulation by the notorious Hacker-tan.
