I actually really liked the story. I think the sensory details were good.
I felt that he really cared for her (IE he wasn't just a puritan hater of technology). She felt like people I've known that spent what was probably too much time in a virtual world. Lots of justification, unwillingness to let go, always dreaming about it etc.
The only complaint I had was I reached the end and was like, where's the rest of it? I kept trying to scroll down. In a good way, I wanted to read more
I wasn't expecting it to end there, even though everything was wrapped up, no loose ends. I was hoping/expecting that she'd recognize how fake the simulation was and give it up.
It was a great story though, nice job.
