Story spark: Perfect Live - Sci-Fi
Living in a perfect world has it's own costs - and what about the people inside and outside

Solution

What price have I to pay to live in a perfect world?

I think about something like an E-book, where the parts, which play in the Perfect-Live-World, are not been told, but are presented as a movie. The two different worlds would be clearer this way. Then the reader could see exactly what Doris and Thomas see on the screen and therefore follow  their train of thoughts. This makes it possible for the reader to better understand their motivation.
