HIM is a story about an AI that gained sentience and slowly corrupts its creator.
I found the story entertaining, but there were various plot points that broke with the suspension of disbelief. Then again, in my case that was because I know what's possible with this kind of technology and what isn't. If you're less tech savvy and you're just looking for a fun story, then this won't be as distracting.
I would have liked it better if there were more thoughts from HIM in the final chapter and as an AI he could have been more calculative and perhaps less emotional. Overall, I didn't get the vibe that he was a program, but more acting like a jealous boyfriend.
Details like those aside, the plot was entertaining to read. On the technical side the story could use another edit. I ran into various mistakes that should be easily fixed.
