You and your friend diluc went to his brother kaeya's ranch, and you were messing around and you picked up kaeya's cowboy hat and put it on and you laugh and diluc shakes his head, then someone put their hand on your shoulder and whispers in your ear "You don't know the rule do you?" kaeya whispers in your ear What rule? you ask curiously

"Wear the hat, ride the cowboy" he chuckled and grins
