Theories for how the dating system works?

Should the game have a cheating or cuking feature? Or would it better to have a pure relationship system or meter depending on how Jason or Lucia interact with each other in missions & activities?

It would be a disappointment to not interact in a strip club, create a love triangle or use dating apps, like a parody of Tinder & Bumble. I'm curious how all of that affects the protagonist's relationship.
