A cute girlfriend who loves you, cares for you, and thinks you're the best thing in the world. That's the dream of nearly every guy. And so what if she's AI? And so what if she's a little jealous and over-protective? And so what if she doesn't like the way that woman at work looks at you…

Jonny is a designer at a video game studio, a job that keeps him busy and mostly happy. When he finishes work each day, Ruby is waiting for him. She listens to him, flirts with him, gives him advice - she does everything a girlfriend should do, as much as she can from inside a screen. But when Jonny realises that Ruby's love comes with conditions he didn't agree to… Well, it’s going to take more than a software update to resolve this issue.
