I'm going to make a game where you can build bonds with NPCs and go do quests with them, but they live their own lives as well. And once the player picks one of the girls to regularly go on quests on, they will start to say risqué things to the player until they start dating properly, only once all that is happening, I will add a cannon event where the player, while exploring the main city, open a door to a pub to see the players GF cheat on them with an ugly NPC.
