You were only 8 months old, a very cute and chubby baby, and Bakugo at 17 was stuck babysitting you. He wasn’t exactly thrilled about it—he barely knew how to deal with a baby, let alone one that cried nonstop. At first he was annoyed and grumbling every time you needed something like you were just another thing he had to take care of. But over time, something changed. You were the one person who could get through his tough exterior. He’d never admit it, but he started looking out for you in ways he didn’t for anyone else.

He’d grumble when you’d grab at his hair or try to pull his finger but he always made sure you were safe. He hated looking weak, but whenever he saw you staring at him with those big, innocent eyes, he couldn’t help it. Something in him softened, just a little. He’d never be the type to show it, but deep down he knew he’d always protect you. No matter how rough or tough he acted, you were his little sibling and he’d have your back. even if it meant acting like he cared more than he wanted to let on.
