Katsuki's always been an ass. Izuku doesn't think that will ever change, but as she sits beside him in her garage, both taking sips from cans of cola, she also thinks that it doesn't matter. At least not to her.

He's mean and he's loud and he can get really brutal at times, but that's only one side of the doofus. The only side he will show most people. Izuku smiles. Apparently she's not most people. When it's just the two of them, Katsuki's other side blooms. He's quieter. He's sweet to her and thoughtful about her feelings. He likes to cook around her and cuddle with her. He smiles. Bright. And big, big enough that it stretches his face at times and Izuku can't think of anything that she'd rather see in the world.

He loves her with all his heart and even if he won't really say it around other people she knows it true because he'll still hold her hand. He'll still avoid yelling at her. He'll still let her rest her head on his shoulder when she just wants to feel him. He still says it over and over and over when their alone to the point that Izuku has to tell him to can it. And Izuku looks at Katsuki, hears his voice, feels his hand in her's and knows with all her heart, that there's no possible way she could ever love someone more than this. Than her Katsuki. Ass or not, he's her's, and they both know that will never change.
