Wouldn’t work as good if set in 2020
The whole calling the home phone number probably wouldn’t connect with people given that many don’t have land lines anymore.
So it would be her ringing his mobile and then finding out her number.

“Oh look, that lady from the party liked my photo...and the next....She’s liked every photo. What’s going on?”
“Put your Instagram to private right now!”
As you can see, not really compelling viewing.
