Youtuber Cyber boi has made his prediction of the story that could be in the GTA 6. We will see if he is right or not after a year. Most likely we will start from a small heist or robbery. It is very possible that after that main character Lucia will end up in prison (as seen in the first trailer) and via all this you will learn how to operate in the game (tutorial). As we can see once she is out of jail on parole with an ankle monitor so this can limit the map at the start of the game. And here we will be introduced with second main character Jason. Jason possibly is a police officer tasked to investigate Lucia and her criminal activity. While things goes to some sort of a relationship Jason has ways to learn more about Lucia. At the further story Jason falls in love with Lucia and then he has a difficult choice either to stick with her or arrest her. Jason chooses Lucia and then the couple has to work they way to have enough money. For deeper explanation of theory check the video above.
