Crusin’ For A Brusin’: Gladio x Reader
You and the royal shield were always butting heads, arguing and snapping at each other like you were an unhappy married couple.
It was always about the littlest of things: Tent placement, how you groomed your hair, snoring.
It was ridiculous.
And it only grew when you two spent more time on the road with the prince, his advisor, and his best friend.
Iris, Gladio’s younger sister always joked around with you, poking fun at how you and Gladio fought. She always pointed out how you were to stutter at him and how Gladio’s cheeks had turned a dusty rose whenever you two finished fighting.
“I think someone has a crush,” she giggled as she plopped down next to you.
“You’re wrong,” you simply stated as you popped open the beer.
“Oh come on! I see the way you two look at each other!” she whined as she got on her knees, scooting over to you so she was in your light of sight.
“What? Spiteful? Hatred? Murderous? Take your pick, Iris, cause it’s anything else but sunshine and rainbows.”
