AN: Ahhh! I feel like a crazy person for wanting to start on yet another Kacchako fic when my plate's already so full but I love this ship so enough is never enough. Lmao. But yeah, this idea has been nagging me for ages and what better time than on Halloween night to get things rolling? I totally missed the uploading deadline there but oh well.

Summary: "W-We used t-t-to be best fri-friends, Katsuki. W-What ch-changed?" Ochako tearfully croaked, clutching her star shaped locket around her neck. "I did! Now get the hell away from me!" the blond fiercely shouted, baring his fangs as he pounded a fist against his chest. It was just his luck to be locked inside a windowless basement with the one person he never wants to hurt while blood deprived. Kacchako. Slight Tododeku/Kirimina. Vampire AU.

Happy reading~ :D

I'm Yours

I Don't Understand

"Honey, what are you doing?" she hears her mother softly chuckling as she entered the bathroom.

A seven-year-old Ochako had scooted a small pink plastic step stool closer to the sink. Her bare feet barely on the step as she leaned in closer to the counter, the skin of her knees being indented with the knob of the sink's cabinet. She closely examined her teeth with her pinkies stretching the corners of her chubby pink cheeks as she loudly hummed an 'ahh,' opening her mouth wide as she possibly could.

She could see her mother's reflection in front of her, the woman standing behind with a curious gleam in her eyes. Licking her canines, Ochako chomped down on her tongue and tried to produce a terrifying roar with her funny expression.

Huffing, Ochako gives up and turns her neck to partially face her mom. "Mama, where are my fangs?" she questions as she tends to do every single night for the past two years. "I want to be like Kacchan!" she reminds her, talking about her best friend who lives 'next' door in the grandiose estate that makes her own house look like a two-story shack. She got in the habit of calling the boy next door Kacchan when she befriended another male in their age range who recently moved into their neighborhood a few months back.

Her mother gently takes her daughter's beautiful long chestnut brown hair and takes a soft bristled brush out of the sink's cabinet to begin brushing her hair. "Oh, Honey, I know how badly you want your own pair of fangs but…" her mother deeply sighed, "we're not like the Bakugou's"

Ochako knew this.

It had been practically drilled into her head since she could remember. She was taught at a young age that the world was so much more than she currently knows of it. There wasn't just humans and animals whom roam their earth. No, there was another species, one that lived between both realms. One that had evolved from death itself into something of tales of immortality and decadent beauty.

"Why can't I be a vampire too?" she purses her lips together in a pout.

Ochako doesn't know what love is but from how her mother explained it and has shown her affections towards her father. She knows in her heart that she feels that way about her best friend. And there was nothing more that she wanted in life other than to stand as his equal.

She's a human. He's a vampire.

They were born into two very different worlds and it didn't seem fair to her at all.

She knows that the eight-year-old-boy won't be coming of age until much, much, later but she already knows that she wasn't made for him. How could he ever want her when she's as fragile as glass in his eyes?

Ochako desires to understand his world but it was the one thing about their friendship that he tried his hardest to keep her in the dark about.

She's been raised in a bubble.

Accepting vampires was one thing as only a small percentage of humans knew of their existence but it was another to fully embrace that sinful, alluring world. She's still so young so of course she would never be allowed near it. Later on, she'd conform to the rules, knowing and understanding her place.

She's privileged – being in that small percentage of people who knows about vampires and is protected by that fact. Her own human family, the Uraraka's have a long-standing friendship and loyalty to the pureblood aristocratic vampire family of the Bakugou's.

While it wasn't as black and white as master and servant, it somewhat felt that way with how close her family lives to the fenced grounds of the estate. Her family wasn't obligated to do anything for her best friend's family but there's been, while infrequent, cases in where she's been awoken by the painful screams of someone suffering in pain.

Her mother would quickly shield her eyes and usher her back to her room whenever she'd come downstairs to investigate. But it was hard to ignore the crimson puddles of blood staining their cherrywood floors as her father rushed a patient into their dining room and quickly slid the doors shut.

This would freak out anyone else but not her. Her father is a doctor and her mother a nurse but they didn't just look at human patients. Most of their private house calls were from vampires.

Ochako shook her head and stared at herself in the mirror. With a big toothy grin, she gave her mother a determined look. "Maybe they'll come in tomorrow! If not, then the night after that or the night after that! I won't give up, Mama!" she dug under the collar of her pink pajama shirt to pull out the chain of her silver star shaped locket and kissed the face of the locket as her secret way of saying she wouldn't give up.

It's something she's had ever since she was born and the only thing she knows about it, is that she's not allowed to take it off no matter what. When she comes of age at sixteen, she'll be able to open the mysterious locket and learn the truth.

Whatever the truth is, escapes her youthful optimistic mind as she concerns herself with other pressing matters such as trying to grow her own pair of fangs.

Ochako continued to check her teeth, never wavering for months. That is, until she turned nine and had a falling-out with her beloved Kacchan.

They were playing right outside in the cul-de-sac. The Bakugou manor being the last estate on the dead-end street. They played as children their age did when Ochako receives the shock of a lifetime.

"I don't want to be your friend anymore, 'Cheeks!" a blond ten-year-old little boy declared one cloudy summer day.

He watched with narrowed ruby red eyes at the shorter girl who was holding onto two snow cones in both hands. The pink and red syrups dripping down her sticky hands as she stared at him wide-eyed.

At first she laughed it off, asking him to please stop pulling jokes on her because it wasn't funny and it was too hot to deal with anything.

"I'm serious! I'm sick and tired of you always following me around like some personal lap dog! Quit it!" he rejected her offered red snow cone, slapping it out of her hand.

She watched in horror as the icy treat immediately began melting away on the asphalt. It wouldn't have been that big of a deal if only it were a normal snow cone but she had added a bit of blood into the red syrup mix from a stash of donated blood her parents allowed her to use.

"Stop calling me Kacchan! That guppy Deku gave me that stupid ass nickname and I hate it!" he wanted to get this done and over with as he eyed her star shaped locket with such a distain in his eyes as if it personally did something to him.

"Why are you acting like this?" she kept her distance, fearing that he'd slap her other snow cone out of her hand if she got any closer. She wouldn't cry, not until she fully understands why he's being so mean to her all of a sudden.

"Don't you get it? You're annoying!" he sneered feeling his fangs threatening to come out, "You're never gonna be a vamp, 'Cheeks so quit acting hopeful for something impossible!" he yelled at her.

In the past, he'd playfully tease her about wanting to be like him but he always remained civil with her. He reminded her to be realistic and to not be disappointed when it didn't happen. He was never so quick to shut her dreams down like how he was doing now. Her dreams seemed silly to him but he never stopped her from believing and now he was saying such hurtful things that were making her blood boil in hurt and anger.

She knows him like the back of her hand, they were best friends. She knows of both his quick temper and his patience – his passion and his sweetness. In that moment, she feels like she's seeing him in a new light because she doesn't know who she's staring at, who she's talking to.

"I… I don't understand," she feels the hot tears well up in her eyes, blurring her vision, "why are you being a total jerk!" she demands, knowing that he won't give her an answer. They've never fought on this scale before. Sure, minor spats here and there but never saying they hate and can't stand each other, or at least not on her part.

"Get the hell outta my face!" he yells yet he's the first one to storm off and leave.

When he's gone, Ochako drops her pink snow cone. She's left on the ground, not caring that the rocky ground scratched her knees, while crying with sticky fingers as she rubbed away at her eyes.

A mess of melting colorful and bloody ice staining her pretty white sundress.

Done! To be continued.

Uhuhu, what's so special about that locket? I do wonder.

I don't know when I'll be able to update this story but this is only the beginning!

Things will become clearer… eventually.

I don't own Ochako Uraraka or Katsuki Bakugou and all other characters used in this fic – Boku No Hero Academia is owned by Kohei Horikoshi.

I just own the idea/plot/story/whatever you want to call it~ lol :P
