I recently started a new game, and I decided that I basically wanted all three of my starting pawns in a poly relationship because well, both because I thought it would be fun and to let me just have them in a single room without it being considered a baracks (sue me), so I used dev stuff in order to just make them all be in a relationship with each other

Issue happened that two weeks into the run, and they broke up with each other, which in retrospect was kind of obvious because I just put them in a relationship and they weren't compatible enough to stay that way

luckily I plopped down a save pretty much right away after having gotten everything just right, out of paranoia that I might eventualy have to restart, so I'm just going to start from scratch again

but I want to do it again and do it right this time, and that means actually going in and trying to change values on certain things in order to make them all more compatible with each other so they actually stay together this time

Problem is I don't know how compatibility is calculated in psychology, and so I do not know what to change or how to change it in order to do that, if anyone knows how psychology does romance stuff, I would very much help some assistance in figuring out how to do this
