I think most people are just hung up on the idea that if you have sex with someone it means you are in a relationship. To me it's just sex, unless I am in a relationship. And yes there is such a thing as experimenting. Women love to use that as an excuse for banging lots of guys. Not sure why, but whatever.
In my case the only LI in any of my playthroughs that MC has slept were Maya, Josy and Sage. The only ones he has fucked are either Quinn's hooker squad, Envy (damn that yummy thing) and Jade. Sage is the only one out of them who has not fucked anyone else (" ...just my toys..."). And in one playthroughs I didn't even get into it with any of them but Sage.Which of the LI is sleeping with someone else? Actual LI and not just a side fuck?
Maya and Josy are obviously together, other than those two who is an actual Love Interest and fucking other people?
To me a Love Interest is someone that they have a planned route to end up with them at the end of the game. As I understand it those are Maya, Josy, Bella, Jill, and Sage... Is there anyone else that the MC can end up with and is a LI?
