Well, regarding Lisa — the main character’s girlfriend — she has a love route where she won’t cheat at all. And on that path, there are no fewer hot scenes than on the cheating route.
As for the factory girls — Amelia and Sophia:
Sophia’s arc implies a romantic line with the main character. So in this case, he would be cheating on Lisa, but if you respond to Sophia in a cold way, nothing will happen.
In Amelia’s arc, there’s an option to protect her from the workers’ advances. Scenes between the main character and Amelia may or may not happen — it all depends on your choices.
Rin has her own path: either she falls in love with the manager and lets him do whatever he wants, or she quits her job and starts streaming, exploring new boundaries.
There are several story arcs in the game that run in parallel. If you get a wasted screen, it means you’ve started a certain storyline and the alternative one has been locked out. The amount of content is roughly the same across all parallel paths.
If you’d like to see all possible routes, I recommend using the chapter selection.
