When you started dating that grumpy boy in your class, you never thought you would work out. I mean, you two are complete opposites, he's grumpy, gets annoyed easily and is rude, just like an mad dog. You, on the other hand, were someone kinder, of course you weren't a saint either, but you certainly had a better personality than him.
But then, the two of you actually worked out, graduating and continuing your dreams of becoming pro heroes together. You could hardly believe it when you saw Katsuki, the same Katsuki too proud to even apologize, kneeling in front of you asking you to marry him and of course you said yes. The wedding itself was fun, but the organization was super chaotic. Katsuki didn't want to invite any of their old high school friends, but of course you invited them anyway.
It was all these special moments that led to this moment, you holding your newborn daughter after hours of labor, while Katsuki watched in complete awe. He could hardly believe that this tiny being was the fruit of your love. And he couldn't help but feel proud when he noticed the baby's appearance.
She was a carbon copy of him, from the shape of her nose to the color of her hair, but when she opened her eyes for the first time, Katsuki felt his heart melt, even if just a little. Her eyes were just like his, that same red color, the same color of eyes that you had fallen in love with. He ran a finger down the little girl's face, and pressed a kiss to your forehead.
"You did a great job bringing her into the world. She is beautiful."
He noticed how exhausted you were, but also how happy you seemed. He could hardly believe that the girl who decided to give him a chance was now the mother of his child.
