Can we have more details on the rivalry between Garen and Darius?

Like i know it most likely started because of rivaled nations but is there more to it?

• How did their rivalry really come to be?
• Do they hate each other?
• Do they have respect for one another?
• How would a typical clash between the two go down?

Just anything about them would be awesome to see. Garen and Darius are my two most favorite top laners to use so i'm pretty invested in anything and everything about them
