If it hadn't been for that accident, ER-1213 should have been dressed as the heroine's sister, a qualified tool to promote the plot.
But now all hell breaks loose.
She becomes the heroine's pet dog,
But the person who replaced her as her sister was an inhuman... Male.
This situation...
If the world collapses and the protagonist turns dark, it's definitely not her fault.
After all, what bad intentions could a puppy have?
PS. In the book, the male and female protagonists are double-crossed, gender changed, and of different races.
