Guys, I know it wouldn't sound so Kacchan-like, but swear I soooo did try my best. Hope you'd like it. xoxo
P.S this is my first fanfic. I'm open for suggestions. Thankisssssss!

Sakura trees were in full bloom that moment. He was wearing a blue All Might hoodie and a grin plastered on his face while a frown on mine. His mother was chit-chatting with my mom and oblivious of our presence. I was upset at mom because I badly wanted to get home already but this other kid in hoodie seemed like he was in a different dimension running around the park.

My frown deepened when he tripped and scraped his knees. He suddenly broke into sobs. And sobs into loud cries. His mom rushed at his side and tried to calm him, whispering motherly sweet words.

Mom then checked on me and asked me what happened. I told her he tripped because he is a klutz. Mom pinched my nose and asked me to be "more friendly". I turned my back and kicked a rock, mumbling " I don't give a crap."

I looked back at the clumsy kid and see him grinning again from ear to ear and his mom smiling adoringly at him. At that exact moment, I was jealous of them. Jealous of him.

I heard mom bid goodbye and saw her kiss the other kid's forehead. The kid waved at me. Tch!
Mom held my hand on our way home. That was rare!

But I was thankful and feeling awkward at the same time.

I can't recall how it really started. However, I think that time all I knew was I was suddenly pulled like an iron caught in a magnetic field.

We shared our kindergarten in the same school, played on the same sandbox and stood on the same ground. We were equal and inseparable. He joined me whenever I go. Either chase and capture butterflies or go fishing. I was always happy to be with him. He was radiating colorful aura and liveliness affecting everyone around him. Teachers adore him and our classmates always want to be with him. We were like sunflowers under the radiant sun. He was such a cute pumpkin with freckles and contagious grin. I felt unwilling to share him to anyone. I wanted his full attention to be on me. Only me. I thought I only wanted to act like a protective big brother even though no one wanted him hurt. I wanted this boy to be just always by my side. I am the tough hero and he's the klutz, still I was always proud to be with him. Always.

He trips, stumbles and falls most of the time. And he cries everytime. He was a pain in the ass. He follows me in every corner and every turn. I told him "Get a life!", but I know it always sounded empty to him because he doesn't leave. And I love that. So much.

I always make him cry. He's a crybaby anyway. But he was a planet and I'm his orbit.

Despite the fact that he couldn't say my name properly. Pronouncing "tsu" as "chu".

I was frustrated teaching him how to properly say my name. Shouting and screaming "KATSUKI!!!".

He started sobbing and managed to say "So-sorry, Ka-Kacchan" in almost a whisper. I stared at him and spat, "You are useless. Really Deku. But fine! Use that."

Deep inside I was glowing. It's cute.

Kirishima, Hanta and Kaminari, those 3 idiots actually made fun of it and asked me why I'm still letting Deku call me that, but I told them to just fuck off and mind their own fucking business.

So, that's part 1. Open for feedbacks! Be nice pleeeeease xD
