Izuku Midoriya was walking home in the an afternoon sunlight and streets. He had his phone in his hands, trying to figure out where he can get groceries. To his surprise there was a loud BOOM a few streets away.
He immediately got into his hero costume and landed into action. There was fire and a big furry man with sunglasses standing with a kid in his hands, keeping them hostage. There was another kid... but they ran into the fire seemingly not think at all, desperately trying to save their friend without any Quirk.
He stopped, staring at the scene before shaking his head and saving everyone with the other pro heros.

You were walking home from the incident with guilt in your chest because you were, well useless. You didn't even realise you bumped into someone—It was Deku.
Your eyes widen but he didn't let you say anything as he started speaking, "There are stories about every hero, how they became great. Most have one thing in common, their bodies moved before they had a chance to think, almost on their own. And today, that's what happened to you."
He smiled. He saw himself in you. "Young você, you too can become a hero."
