Deku for the First Time

Katsuki doesn't know how or why it happened. But somehow he's back again. Back to the day, he called Izuku "Deku" and made him cry for the first time.

He rushes over, to the lone crying 4 year old boy, who's still standing at the spot little Katsuki left him.
Katsuki's heart cracks with each sob he hears.

The sobs lessen as Izuku hears footsteps approaching him, and he freezes when he realizes a man is running towards him.

Katsuki stops a few steps away from the boy. Panting from his sprint, he takes a closer look at his little face. Puffy green eyes look up at him, clearly frightened. His small frame begins to tremble.

A surge of panic shoots through Katsuki, he didn't think before running. Fuck now he scared the boy!

"Izu-" Katsuki breathes out. And lowers himself to the ground to be face to face with him.

"Izuku I'm sorry for scaring you”

Izuku's eyebrows scrunch up when he looks up at him. "y..you.. know me?"  The boy stutters out.

This time it's Katsuki who freezes.

Oh, fuck.

He mentally slaps himself for his thoughtless actions. He doesn't know how he landed here but f movies thought him one thing it's that you're not supposed to interact with anyone in the past. As he debates what to do, he misses little izukus eyes widening and the little boy taking a few tentative steps forward. He feels a tiny hand touch his knee and looks down to see The boy looking up at him with wide eyes. "you.. You look like Kacchan” the boy says.

And fuck, no use denying it now, 4 year old Izuku is apparently as perceptive as 23 year old Izuku.

"I am"

"are you a hero?” Izuku asks, his eyes sparkling.

"I am" Katsuki responds smiling.

Izuku's eyes begin to mist and a big tear rolls down his chubby cheeks.

“Of course Kacchan made it! He's the coolest.” he says, rubbing his eyes.

He takes a second, clearly thinking about how to say what's on his mind. Biting his trembling lips, he looks down before tentatively and quietly speaking again, “my Kacchan doesn't want me anymore because I'm" He hiccups on his upcoming sob and starts the sentence anew.

"Are b-big Kacchan and b-big me friends again even though I'm useless?" little Izuku sobs out.

And if movies taught Katsuki another thing, it's that you're not supposed to touch anything and anyone in the past.

But fuck that. Whatever the consequences of breaking these rules, may be they couldn't possibly be worse than his heart finally breaking in two.

He rushed forward and wrapped the little boy in his arms, burying his face in soft green curls. “You made it too!“ He shouted.

"You made it too Izuku!" hugging the boy tighter, he continued. “You're a hero too! One of the best! And we're partners! Don't believe little me you're not.." his own voice cracked at that, "You're not useless!"

Izuku squirms in his arms, but Katsuki doesn't dare let go. "but - but I'm quirkless"

Fuck.

Now that he thinks about it...
This was the day Izuku broke the news that he was quirkless, which must mean he had found out not too long ago himself. His eyes stung.

"You're not quirkless in the future, Izu! And even if u were-you would've made it as a Hero!” Katsuki cries out. He can taste his own tears that are steadily streaming down his face.
