About: I've wanted to write a soulmate AU for a while now, but this one's a bit different than the usual 'I'm getting old and I still haven't found my soulmate even though everyone else has' soulmate story (not that I don't like those).

It had been happening for years now. Some mornings, Lucy would wake up and find black ink scribbled up and down her left arm. At first, she thought it was just a prank. Maybe one of her friends had been sneaking into her house and drawing on her. But when she asked, they all said it wasn't them. Levy, for probably the first time ever, had no clue what was going on. Juvia and Mirajane went on and on about a soulmate or a secret lover. Meanwhile Erza was arguing with Lucy about whether or not to call the cops.

Whoever was doing it, Lucy decided, wasn't doing it to prank her. Otherwise they would have drawn things other than simple patterns that spiraled like DNA and the occasional flame-like symbol, which were usually done with red and orange pen instead of black. Maybe if it were a prank there would be writing involved as well. Maybe if she tried leaving this mystery person a message, they would leave her alone.

Lucy walked over to her desk and pulled open her top right drawer to fetch her favorite rose-colored ink pen. Without even thinking, she uncapped the pen and placed the tip above her left hand.

"I'm so going to regret this," Lucy muttered to herself. In normal circumstances, pen ink was relatively easy to wash off of skin. However, in the past when Lucy tried to erase the black ink off her arm, it wouldn't come off. It would just disappear a few days later like it was all a dream.

Lucy's pen hovered over her hand and, instead of thinking though what she was going to write, she impulsively wrote the simplest thing she could.

"I'll just be gone for the weekend, no big deal. Just promise you won't break anything while I'm gone."

"Yeah, whatever."

"I'm serious, Natsu! If I get one more call from Wendy saying that you broke the lamp again you're getting kicked out."

Natsu, the man being lectured, swung his legs on top of the table and rested his arms behind his head. "It only happened twice, Gray, get over it."

Natsu's roommate, Gray Fullbuster, turned around to leave but then stopped and turned back around suddenly. "One last thing-" he said before he saw a speck of something pink on Natsu's left hand. Gray completely forgot whatever it was he was about to say. "What is that?" he said, gesturing to Natsu's left hand.

Natsu brought his arms in front of him to inspect his hand. "What is wha-" he started to say before he saw it too. There, on his left hand, was the word 'hi' in a cursive-like font in a bright pink color.

"Well anyways," Gray said, bringing Natsu's attention back to himself, "I should get going now or I'll be late. See ya," Gray gave Natsu a small wave before leaving their apartment. Natsu was left alone and he began to think about why someone would write 'hi' on his hand. The first person he thought of was Gray, it could have been a quick joke before he left. But Natsu quickly dismissed the idea, he was pretty sure Gray didn't own a pink pen. The last time he saw his cousin Wendy was three days ago, and since the writing appeared this morning it couldn't be her. Maybe some kind of ninja or something snuck into his room while he wasn't looking! Natsu gave up on that idea as well, and decided that maybe he should cut back on the action movies.

Not knowing what else to do, Natsu grabbed the black pen that he liked to draw on his skin with and write on his right arm. It was a bit difficult, since Natsu is right-handed not left, but when he was finished the word 'hello' with a question mark at the end was written in a sloppy but still readable font.

Lucy Heartfilia was mentally facepalming after re-reading what she had wrote on her hand. She could have gone with 'who are you?', 'why are you drawing on me?', or even a 'I'll call the cops if you keep this up' would have been better than the simple two letter word she went with. Lucy considered scribbling it out and writing something else, but she didn't want to take up too much space incase she needed to write more later. So instead of dwelling on the past, she picked up her journal and continued writing her soon-to-be novel. She wasn't what someone would call a famous writer, but she did have a good number of fans and she truly enjoys her job. After the weird events from earlier, she thought now would be a good time to settle down a bit. The ideas were coming easily and she soon lost herself in her writing.

After writing for a good hour, Lucy had finished her last chapter and was halfway down the left side page of the next one. Her right arm was stretched across the blank right side in the most comfortable way possible for writing. However, Lucy stopped writing when she felt a soft brush on her right arm. Lucy looked away from the page to her arm to see if something was wrong or if it was simply a fly that had flown in through her open window. She froze when she saw the familiar black ink spelling out 'hello?' on her right forearm. She had just turned the last page a second ago, and it wasn't there then so how did it get there?

Lucy placed her pen inside her notebook to keep the page and set it down on the couch before reaching to the phone on the table. She didn't know who to call, so she just dialed the last person who called. The phone rang a few times before it was picked up and a voice spoke on the other end.

"Hello Lucy. Do you need something?" the voice of Erza Scarlet came through her phone's speaker. In hindsight, Erza probably wasn't the best person to call for the situation, but Lucy had to talk to someone.

"Yeah I do. Do you remember that drawing on my arm I was asking you about?"

"Yes. Did you find out who did it?"

"No, but…" Lucy's voice trailed off as she choose her words carefully. She calmly told Erza about writing on her hand and the ghostly-like response.

"I see…" Erza said as she processed the information, "Well did you write back?"

"Write back?"

"Aren't they expecting a response?"

Lucy thought about it for a bit. Maybe if they continued to write back and forth, she would be able to find out who this person is.

"Yeah you're right. I'll do that now, thanks Erza!" Lucy spoke back, realizing she was still on the phone.

"No problem. Good luck," Erza said before ending the call.

Lucy hung up her end and threw her phone beside down onto the couch. She flopped down next to it and sighed while trying to think of what was happening and what she should write back. She already knew that it was impossible for someone to be sneaking into her house because of how fast the word appeared before. Ever since she was a little girl, Lucy always believed that there was magic in the world. It was never something that she grew out of. Besides, there was no other possible explanation for what was going on.

Lucy reached to her desk and grabbed her pink pen once again. Now that she had some time to think, she was able to write a full sentence to whomever it was sending and receiving messages.

'Do you know what's going on?'

Natsu didn't know what he was expecting to happen, but when those six words appeared on his left arm out of nowhere, he panicked a little. There was no way someone could have gotten in his appartment, wrote on his arm, and got back out before he could notice. He would have begun thinking for a reasonable explanation, but he wanted quick answers.

Natsu hit the mute button on his TV so he could focus. Whoever this was, they seemed to be just as confused as him. Natsu picked his pen back up and quickly wrote his response under where the mystery person had previously written.

'No I don't. Who is this?'

It appeared almost magically, just like the last one. Maybe it was magic. Lucy remembered Levy telling her about how in some of the books she's read two people would meet by marks appearing on their skin. Levy had said that they were soulmates if they had the same marks. Lucy's situation seemed similar. Could the book that Levy was talking about be real? Lucy picked her phone back up that was still next to her after her phone call with Erza. She sent Levy a quick text, telling her to come over as soon as possible.

Lucy took a few deep breaths and started to write on her arm again.

'Lucy Heartfilia. And you are…?'

Lucy. Their name is Lucy and judging from the feminine-sounding name, he could tell that Lucy was a girl. Natsu pulled his laptop onto him, which was still on from when he was using it to Skype his friend earlier, and opened up his internet browser to do a quick search on Lucy Heartfilia. He didn't do it to find anything personal, he just wanted to know more about this person and why the two of them could communicate this way.

While waiting for the webpage to load, he quickly wrote a response to Lucy.

Lucy got up from her couch when she heard a soft knock on her door. When she opened it, she was face to face with a very excited Levy McGarden.

"I got your text so I came over as fast as I could," she said with a bright smile.

"Thanks for coming! I was wondering if you could help me with something," Lucy smiled back and closed the door after Levy was inside.

"Sure, what is it?" Levy asked enthusiastically.

Lucy updated Levy on everything that had happened since the last time they talked.

"So I guess Juvia and Mira were right then," Levy teased, "He must be your soulmate! This is so exciting!"

"Yeah but I don't-" before Lucy could finish, she felt a familiar sensation on her left arm. When she looked, she noticed that her arm was almost completely covered in pen. She looked for the new markings, and read the results out loud.

"Natsu Dragneel," she whispered just loud enough for Levy to hear.

"Natsu, huh? Judging from the handwriting I would guess it's a boy, but isn't Natsu a girl's name?" Levy asked.

"I think Natsu's a he. A girl probably would have drawn flowers or something prettier on her arm if anything, not fire," Lucy responded, still staring at the name written on her arm.

When Lucy looks up, she sees Levy give her a little nod as she's typing something into her phone. Lucy stands behind Levy to peek at her screen.

"Levy! I don't want to stalk him!" Lucy screeches, trying to pry the phone out of Levy's hands when she sees Levy typing the 'n' in 'Dragneel'.

"I'm just trying to find out if he lives anywhere near here so you two can meet up," Levy pouts after letting go of her phone.

"Meet up?"

"Well duh! You're soulmates," Levy exclaims with a shine in her eye.

Lucy wanted to believe Levy about the soulmates thing, but it was difficult. Of all the people in the world, why would this happen to her? "Fine, you can see what city he lives in, but that's it," Lucy gives in and hands the phone back to Levy. Levy giggles and types in the search.

"Lucy Heartfilia is the bestselling author of…" Natsu begins to read her Wikipedia page but stops when he notices more pink letters appear on his right arm.

'Meet me at Magnolia Station 7pm'

Magnolia Station was about half an hour from Natsu's apartment. He gazed to the lower right-hand corner of his computer screen to check the time. It was already almost 6, so he started to get ready. But before that he wrote back a quick 'ok see you there' under her message.

Natsu was usually a pretty upbeat yet calm guy. However, today was different. He never would have expected that somehow, by writing on his skin, he can send messages to someone. He was even more stressed because he didn't have Gray to fall back on or give him advice. Natsu had heard, probably in a TV commercial or some movie ad, about a story where everyone could do what he and Lucy just did. Of course, when he heard it, he thought it was fake. He wasn't completely wrong though, the other billions of people in the world couldn't communicate by writing on their skin but somehow he and Lucy could.

Natsu decided that he should be going soon, so he quickly threw on some clothes, nothing too fancy, and grabbed a couple pens, just in case. He gave his cat Happy once last pat on the head -which, when asked, he would claim it was for good luck- and left his apartment.

"I can't believe you made me do that."

"I thought you wanted to meet him!"

"Levy…"

"I'll leave so you can get ready."

"Levy!"

The door closed and Lucy was once again alone. After finding out that Natsu lived in the neighboring city -what are the odds of that?- Levy convinced Lucy that the two should meet up halfway. Halfway being Magnolia Station. After Lucy agreed, she wrote on her arm to let Natsu know and the responce 'ok see you there' came soon after.

After Levy left, Lucy walked back to her room and all through her closet, trying to find what she was going to wear. She wondered what someone was supposed to wear when they were going to meet their so-called 'soulmate'. Lucy pondered this for a while, but eventually decided to wear a simple outfit, a pink T-shirt with a black mini-skirt and heels. Nice, but not too nice.

Lucy quickly got dressed, then grabbed her phone and car keys. Gazing at the clock in her living room, Lucy found out that it was 6:25 and she should get going.

In hindsight, Natsu probably should've asked where in Magnolia Station they should meet. It was a large building, and not only that it was very loud with all the people crowded in it. Natsu didn't even know what the girl looked like; her Wiki page didn't have a picture. It was exactly 7pm and, as if on cue, he noticed words begin to appear on his arm.

'Look behind you'

Natsu turned around to the crowd of people behind him. She was relatively easy to spot with all the writing on both her arms. He figured that the writing was how she knew it was him as well. Natsu waved to his so-called 'soulmate' and couldn't help but smile because her shirt was the same color as her ink.

A/N: I'm considering writing a part two with an in-depth meeting and what happens after they meet. I already have a couple ideas for it but I want to know what you all think. Let me know if you want me to!
