"Natsu!"

The pink-haired boy cringed at the sound of the high-pitched screech, also known as his new pre-school teacher. He threw his hands up in mock defense, "It wasn't my fault! He took my lego piece!"

Said middle-aged woman sighed, shaking her head in defeat, "Biting him isn't the nice way of getting it back though. We've went over this before, Natsu. Go sit in the corner for five." She pointed but Natsu didn't need the guidance, him and the 'corner' were well acquainted.

The five year old stomped his way over to the 'corner' before he slumped down, facing the corner of the wall in a cross-legged manner. Today was not his day. First his foster dad yelled at him for something that was not his fault and how he was getting harped at by the pre-school lady too.

Before Natsu could dwell longer on his five-year-old angst and pout some more, a paper airplane came zooming by, hitting him in the back of his head. The pink-haired boy growled before turning around sharply, scanning the room for his attacker. They would pay.

But what he did not expect was to see a blonde, brown-eyed girl across the room running over to him, worry in her eyes, "Oh I'm so sorry! I was practicing...I didn't mean to hit you. I'm sorry."

Natsu was flustered at the girl's incessant apologies, blushing a little as he picked up the paper creation, handing it back to her, "S'okay."

She smiled, "Thanks."

Then she noticed where they were in the classroom, "Are you in trouble?"

Natsu frowned, his eyes darkening as he turned back around to face the corner, hoping the girl would take the hint and leave him alone, "What does it look like? Go away."

The blonde girl pouted at his behavior, "It was just a question."

"Well who asked-?" Natsu turned to glare at her but was stopped when she flicked his forehead.

The girl gasped, "Oh I'm sorry!"

"What was that for?!" Natsu screeched, feeling tears prick his eyes as he held his forehead clasped behind both of his hands.

"I'm sorry! You weren't supposed to turn around!" The girl complained, angered at the boy's sudden movement; she had meant to flick the back of his head which would have been a lot less painful, but the boy had to go and turn around on her.

"Oh so it's my fault you flicked my forehead? You could've just not flicked anything at all!" Natsu grumbled, standing up to face the girl and forgot the fact that he was supposed to be in 'time out'.

The girl placed her hands on her hips, "Well who asked you?! Boys are so stupid."

"Stupid? Me?! Girls are stupider! You're the one who can't fly a paper airplane right." Natsu growled back, stepping closer to the girl in hopes of intimidating her. But she would have none of that as she stepped even closer, their foreheads almost touching and their eyes glaring at each other.

"Natsu, Lucy!"

The two children instantly deflated at the sound of their aggravated pre-school teacher. They twirled around in time to watch as the woman walked towards them looking none too impressed at their screaming match, "What on earth are you two doing? Natsu you're supposed to be in 'time out' and Lucy, you know we are not supposed to play with someone when they're in trouble."

"I wasn't playing with him!" Lucy whined.

"I was until she came over and ruined everything!" Natsu screamed at the same time.

The pre-school teacher sighed, not wanting to deal with these two troublemakers. Why was it always them? If it wasn't Natsu causing mischief then it was this blonde alter ego of his, "Natsu, you will be here for another ten minutes and Lucy? You'll be joining him. No questions, buts, or complaints. Sit down now and I will not hear a peep out of either of you, understood?"

The two children opened their mouths as if to complain but were shut right up at the teacher's evil glare, "Sit."

They grumbled and turned towards the wall in silence, sitting down.

Natsu sighed.

This day was just getting worse. Now he had a whole ten minutes more onto his 'timeout' and he was no longer alone: who was this kid anyways? This was why he hated girls. They only caused more problems for him.

"Hey, psst."

The boy glanced over and saw the blonde girl covering her mouth with her hand, hiding the fact that she was talking away from their teacher, "What now?" He grumbled, not wanting to get in trouble again because of this girl.

The girl blushed and frowned, looking at the ground in between them before replying, "I'm sorry. I got you more in trouble."

Natsu blushed at the girl's apology, not expecting it from the fiery girl, "Umm, it's okay," he scratched his cheek in embarrassment, "I'm sorry too I guess."

The girl looked back at him before beaming his way. Natsu suddenly felt it get hot as his cheeks burned a new shade of red, who was this girl? "What's your name?"

"Natsu. What's yours?"

The blonde's smile widened as she gave him her hand in hopes he would shake it, "I'm Lucy, wanna be friends?"

Natsu stared at her hand before returning to Lucy's smiling face. The pink-haired boy smiled slowly then outright grinned, showing off his canines, before taking her hand in his and shaking it, "Okay, nice to meet you Luce."

Maybe today was not the worst day ever after all.

A/N: There's something about the Fairy Tail characters as children that I always love. Side note though: I know I have this one shot as 'complete' but I maaaaay or maaay not update this once in awhile with other adventures that Lucy and Natsu might have as children growing up in this random AU I have in my head. So you might want to follow this if you want to see if I do update or not...I don't know, it's up to you. ;)
