Katherine and Marcus met while they were both stuck in a dystopian future where kids have to fight to the death as entertainment for the wealthy. When Marcus didn’t immediately kill Katherine, she knew he was someone special. They teamed up to fight the bad guys and even stood up to the fascist government by refusing to kill each other after they defeated everyone else. Their love story continued on in order to make more movies and eventually they settled back in their original home district living happily ever after. Wait, thats the love story in Hunger Games. They met online. Marcus ended up not being a pyscho killer and Katherine ended up actually looking like her photos.
