A five-year-old Katsuki remembers the day exactly. How could he forget? The day he met the love of his life, Izuku Midoriya. It was his birthday; he was turning three. His mom and dad took him to his favorite park to spend the morning. Katsuki ran to the slides right when they got there, and he reached the top of the latter. But he saw him. Bright green eyes, freckles and curly dark green hair. The boy turned to him and nervously smiled.
"H-Hello..."
Katsuki's heart squeezed. He quickly got off the latter and stood in front of the boy, who let out a nervous squeak.
"Hey! What're you doing here hah?!"
The boy stammered, shifting on his legs.
"W-well i was g-going on the slide..."
The boy looked at Katsuki, then noticed the button on Katsuki's shirt. It was big, with the words 'Birthday Boy' in cursive letters and little confetti's around it. The boy smiles, his eyes shining.
"Its your birthday today?! Oh wow! How old are you turning?! Thats so cool!"
Katsuki's eyes widen at the boys excited expression and his ears dust pink.
"I-I'm turning three today! Damn right its cool!"
The boy smiles again and Katsuki stares. The boy looks down again.
"U-Um... My n-name is I-Izuku Midoriya... W-What's yours...?"
Izuku Midoriya Izuku Midoriya Izuku Midoriya
Katsuki plays with the name in his head. It feels... Right. Katsuki can't find the words to describe how or why, it just does.
"Names Katsuki Bakugou."
Izuku smiles.
"Nice to meet you K-Ka-"
"Katsuki."
"Ka-K-Ka-"
"Ka, tsu, ki."
"Ka-Ka-Kacchan!"
Bakugou just stares.
"What the fuck is a kacchan. You making fun of me or something?! Is that it?!"
Izuku puts his hands up.
"N-No of course n-not!"
Izuku hides behind his arms.
"I-It's just that... I c-can't really say it well a-and.."
Katsuki tchs, folding his arms.
"Alright whatever. But in exchange for calling me 'kacchan', you gotta do everything i say, got it?!"
Izuku takes a moment to process the demand, then breaks out in a wide smile.
"Ok Kacchan!"
Katsuki smirks and is preparing to go down the slide, looking at the slide, looking at Izuku.
"Follow me, Izu! We're gonna go play on the swings!"
After that, they begin to play together every day and have sleepovers at each other's houses. They were joined at the hip, never leaving each other's side unless they were forced to. Months went by like this, the two spending every minute they could together. Then it happened. The incident.
Katsuki walks into the classroom, backpack slung over his shoulder. He had been dropped off late to school because he overslept and missed the bus. Not really a big mistake for a three-year-old, Katsuki was still getting used to the whole idea of waking up early to go somewhere with so many extras. Katsuki looks around the classroom, expecting to see Izuku sitting alone next to his seat, dutifully waiting for Katsuki to walk in. But what he saw instead sent his blood boiling, palms sweating, and eyes narrowing in thousands of negative emotions. Izuku was playing with all might figures, some extra sitting next to him, holding another all might.
