Yes, that's the proposal of the game. Every time you agree on doing something with an NPC, there's a hidden stat that raises Reya's affinity to that character. In time, you'll be able to start a relationship with that NPC. But at the same time, you'll be able to have relationship with other characters. Some of them are jealous, others will like to be cucked. Some will never know what's happening, because the player will have choices to make in the game that affects how people will react to her actions.
Reya will be able to divorce, have children and have jobs. The script for this is already done, just waiting for implementing when the time comes =3
