So... the other day I was listening to Mary's song (Oh my, my, my) by Taylor Swift and well, this idea came up. This is just a short prologue but if you like it I'll be uploading the first chapter soon :) Sorry for my mistakes!

Just to make clear, Elena and Katherine are twins and they're Isobel and Grayson's daughters, but they live with Grayson and Miranda. Jeremy is Grayson and Miranda's son.

Disclaimer: I don't own the vampire diaries or any of its characters. :(

She said, I was seven and you were nine

I looked at you like the stars that shine

In the sky, the pretty lights

And our daddies used to joke about the two of us,

growing up and falling in love

and our mammas smiled and rolled their eyes,

and said oh, my, my, my...

-Taylor Swift Mary's song

Flashback. Ten years ago...

"You're so slow, Stefan!" Seven-year-old Katherine shouted, as she ran along the forest wearing an impeccable white dress and a matching hair-band.

"Shut up, you cheated!" Nine-year-old Stefan said, running behind her in his little suit. Then he saw her climbing a short fence. "Hey! We're not supposed to go there!"

"Who cares?!" Katherine said as he arrived where she was and saw how she quickly passed to the other side of the fence, where there was a field full of mulberries. "Come on, Stefan!"

"Katie, our parents are gonna get mad!" Stefan told her.

"You're a chicken!" She told him, challenging him.

"I am not!" Stefan said, getting a little pissed.

"Then come here!" She insisted.

"It's your aunt's wedding! We'll strain our clothes and our moms will be mad!" Stefan said and Katherine rolled her eyes.

"Fine, I'll go by myself." She said, starting to walk to the field.

Stefan doubted for a moment if he should go behind her or not. His mother had given him clear instructions: Do not strain your suit. Do not go to the forest. Do not cross the 'forbidden' fence. And then Miranda had come, and said the same to Katherine. He always tried to follow the rules, but having Katie as his best friend made it difficult to do what he was told.

He shouldn't be crossing that fence, but, on the other hand, it looked like fun. Besides he couldn't just leave Katie alone...

Maybe he could just play and not strain his suit and their parents wouldn't even notice they'd been there.

He climbed up the fence and crossed to the other side, and Katie smiled widely when she saw him.

"Finally!" She said. "I'll race you to that tree!" She pointed at a mulberry which was some meters away from them.

"You know I'll beat you, I'm bigger than you" Stefan told her.

"Well, let's see that... at the count of three..." She said as they got ready. "One... two..." She suddenly started running. "Three!"

"Hey, that's not fair stop cheating!" He complained as he ran behind her. She was always cheating because she just hated losing. Stefan had got used to that but it was sometimes really annoying because she'd never let him win, not a single time.

She finally arrived before him and then said. "Ha! I win!"

"That's not fair you always cheat!" Stefan said, a little pissed off.

"Not true"

"Yes it is"

"No it's not!"

"Yes it is!" Stefan insisted. "And you know I'd beat you if you didn't do that because you're a dwarf!"

Katie pouted. "Miranda says I'm gonna grow as big as her"

"We'll see that"

"Don't be mean!"

"What?! You're shorter than Lena, aren't you? And you're the same age" Stefan said and when Katie lowered her gaze he quickly added. "But you're the prettiest one"

She smiled widely at him again. "Thanks"

"You're welcome" He said as he looked up to the blackberries which were growing on the tree. "I'm hungry. Let's grab some of those"

Katherine nodded and a moment later Stefan was helping her climb up, as she was at least eight inches shorter than him. Then he climbed too and they both sat on a branch.

Stefan started pulling out some blackberries as Katie stayed deep in thought for a while.

"Stefan, can I ask you a question?" She said suddenly, while Stefan continued being entertained pulling out the blackberries.

"Sure"

"Do you think that my mamma is never here because of that?" She asked him and he raised his gaze from the blackberries to look at her. "Because I'm too short? Maybe nobody told her that I'll grow up and I'll be bigger"

"I don't think that's the reason, Katie" Stefan told her and she lowered her gaze.

"Then why didn't she come for Christmas this year?" She asked, grabbing some blackberries. "What have I done wrong? I did my homework and I have been behaving well... most of the time"

"I don't think you have done anything wrong" Stefan told her and she looked at him. "Neither did Lena. I just think your mom is the one who's doing things wrong"

"Why?" Katherine asked him. "I mean, I understand with Elena... everyone says she's such a good girl... but all I bring to my dad and Miranda is trouble"

"That's not true" Stefan scoffed. "I think you're kind of amazing"

"You think so?" She asked him, smiling again.

"Yeah" He said, giving her a blackberry. "You sing very nice, are funnier than the rest of the girls and your hair smells good."

"Really?" She asked, taking a stray of her hair and smelling it.

"Yeah, like strawberries"

"Wow" She said, letting her hair go and looking at him and he looked quickly away and grabbed another blackberry.

"Of course, that's just sometimes" He said and then added. "Most of the time you're just annoying"

She giggled as she threw him a blackberry to his hair. "Shut up!"

"Katie, Stefan, where are you?!" They suddenly heard Maria's voice say and both of them looked at each other in horror before climbing off the tree.

They ran as fast as they could towards the fence, until they saw Maria and Miranda standing behind it, crossing their arms and looking rather pissed.

But when Miranda looked at Katherine's -now purple- dress she really went completely mad.

"KATERINA SERENA GILBERT!" Miranda shouted at her. "WHAT DID YOU DO TO YOUR DRESS?!"
