The phrase "losing the plot" gets thrown around a lot, but it's not often I see it so literally. Who are these characters? What the fuck is even going on? Why are we supposed to care? What happened to the story?
This reads like the mangaka originally wanted to write a dystopian drama about android rights and morality, got rejected by the publisher and told to retool it for broader appeal, made it into a robot love story, and now that he's all cushy and published with a contract, he's hijacking his own manga to write the story he originally wanted. What a weird and nonsensical set of turns.
