The first time Katsuki Bakugou saw the little girl named Izuku Midoriya they weren't older than 4 years old.

And even if he would never admit it -mainly to his mother- the first word that popped in his head when he saw her was 'cute'.

Don't get him wrong, the last thing that it was, was shyness. It was only him trying to go against what his mother had been saying about the girl during all the way to the Midoriya house.

"Good morning, Inko-san, it has been a long time." Mitsuki greeted the green-haired woman.

"It has been, Mitsuki-san, Masaru-kun," Inko said with a smile, her hand on the green-haired, green-eyed girl that popped behind her, "is this the famous Katsuki I've been hearing about?" She pointed towards the ash-haired boy.

"It is," his mother said pushing him towards the mother and daughter.

"Stop it, old hag" he hissed knowing very well that his mother would say some kind of profanity right back at him.

But before she could Inko laughed nervously and gestured for the three guests to come inside.

Their host guided them towards the living room. Inko signalled them to sit down as Izuku went to the kitchen, bringing with her a silver tray with three cups and a kettle.

The young girl set the tray down in the small table and poured the tea on the cups.

"Thanks, Izuku!" Her mother said, kissing her cheek.

His mother cooed at the girl saying something along the lines of: 'she is so cute', 'I want a daughter-in-law just like her' and 'Why can't you be cute like that Katsuki?'

Most of that stroke his ego.

"Izu-chan," his mother called out, "did you get your quirk yet?"

That picked his interest.

Izuku looked at her mother nervously as the woman said: "No, Izuku's quirkless,"

'Quirkless?' Katsuki thought, 'that means she is useless,'

"Oh, I'm sorry, sweetheart," his father said.

"There's no problem uncle Masaru, I'll be a hero anyway," she smiled, then with a curious look she asked Katsuki, "What's your quirk?"

He smirked and held his small hand out making small explosions.

Her eyes lit up as she praised him.

The rest of the conversation between his parents and their host was about their work so he cancelled their voice out.

Until the little girl pulled at her mother's apron and whispered something in her ear.

"Of course sweetheart," her mother replied than looking at him she said, "Why don't you take Katsuki-kun with you?"

The girl looked at him and smiled brightly and nodded, jumping out of her spot on the sofa.

"Come on, Kacchan let's play," she said happily not really waiting for him.

He stared at her then at his cackling mother, before following the girl out of the room, scowling.

Izuku had to admit, her room was an All Might shrine. Even if she was only 4, she had a lot of things that were somehow related to the number 1 hero.

Because of him she already knew what she wanted to do when she grew up.

She wanted to be a hero that saved people with a fearless smile.

"I see that you like All Might," Katsuki said looking at her room.

"Of course I like him, he's the greatest hero, he always saves everyone with a smile, and I want to be just like him!" The girl struck a pose just like the poster behind her.

"Hahahahaha" the boy laughed, "you? Like All Might? But he is super big like this-" he gestured with his tiny arms.

The girl looked down tears forming in her eyes.

The boy panicked, his mother was going to kill him if she discovers he made the girl cry. He thought quickly, what could he say that wouldn't worsen the situation?

"But that doesn't mean you can't be a hero," he tried, she looked up confused, "you can be my sidekick!" He pointed at himself.

The girl squinted at him, making him blush when he saw a smile form on her lips that made her eyes shine like emeralds.

'Yeah,' he thought 'definitely not going to tell the old hag that she's cute'.
