The devs need to nerf this mechanism as it has become unmanageable now.
Dev, singular. Tinkerer does it all himself. Well, almost...he has help for animations. And a QA person who checks things before test builds are released to higher-tier supporters.
The Affection Cheat IS a built-in nerf, if you turn it on you don't even have to use Awe (unless you want to). It's up to the individual player whether to use the cheat or not.
You can absolutely keep all the girls happy without using either the cheat or Awe, and still have time for other stuff. You sleep at a different LI's place pretty much every night and fuck every LI located there, but there's a 15-day grace before Affection starts dropping and fewer sleeping places than that. Sleeping+fucking+a gift when you do show up is generally sufficient to refill Affection fully even after a 20+ day absence. Some LIs' timers aren't tied to sleeping with them; a couple don't have a grace period at all, they lose (a very small amount of) Affection daily starting immediately.
It's still a pattern/routine/schedule to follow and some players aren't interested in doing that. And TBH there's not a lot of wiggle room left to add more LIs requiring sleeps...
