AN : Sorry for the wait!

Also, as I already said, English is not my native language so I don't know how to write a song but I tried because it was an important part of the scene between Lucy and Gajeel. So feel free to correct or make suggestion to make it better! ;)

Enjoy!

Chapter 4 : The way you smile

What can she do now?

Lucy was dragged by Gajeel, it was too soon to ask Levy for information and Natsu and Gray were in a fight with some others men from the guild.

"Lucy!" Someone called behind her and she turned around immediately. Was she already used to be Lucy she reacted so quickly with Lucy's name being called?

Cana was waving at her, a vine bottle in hand. Juvia went to her with a smile. As soon as she was seated across her, Cana handed her a cup.

"So, how was it last night?" The brunette said with a wink.

"Huh?"

"Did you manage to push away the two others and enjoy your time with him?"

What was she talking about? Juvia was completely lost.

"Oh, come on!" Cana pressed. "It's not like you to be this shy! Besides, it's only fair after I gave you my best advices!"

"Huh… well…"

"Did he kiss you?"

"Huh…No…"

For gods why was this happening to her?! Who was the man she was talking about? Natsu? Gray? Loke? Juvia was quickly reviewing her love map in her mind to find Lucy's lover but the image of Natsu's face was persistent.

"Ah, poor child." Cana sympathized. "You're not so lucky when it comes to love. Your case is almost as complicated as Juvia's. Did you follow my suggestion about underwear? A pink see-through bra and a panty with lace and a bow on the front."

Juvia blushed furiously. She didn't know what to say. Lucy said nothing to her about it. And did Cana really think that her love situation was hopeless?

"Good morning Lucy-san! Cana-san!"

If she had not refrain herself, she would have crush Wendy with a hug for her great timing.

"Good morning Wendy! Carla!" She greeted the petite dragon slayer and the white exceed who accompanied her as always.

"They are already in a fight? That a noisy guild!" Carla sighed as she watched the men.

"Hey Wendy! Want a drink?" Cana offered.

"Erm… No, thank you" The girl declined.

"You don't know what you miss. It's more faithful than men. Oi, Lucy! You didn't touch yours!"

"Ye…yeah." Juvia complied and took a tiny sip. She didn't want to upset Cana but she didn't want to be drunk when she had to watch her words and act as Lucy.

What was Lucy doing right now? Did she have as much difficulties as Juvia?

###

Lucy was sitting on Gajeel's couch, looking around her. She had never come to Gajeel's place before. Surprisingly, it was clean and tidy. It was probably Lily's work. She had some difficulties to imagine Gajeel in a neat freak.

The said man came back from his bedroom with papers in hand.

"Here. " He said and put the papers on his coffee table before her. "I wrote this last night. It's just the beginning of the song. I have the tune already. Your job is to find more sentences."

"Okay…" Lucy answered unsure of what to say. "Can you remind me what is this song about?"

Much to her surprise, he blushed deeply.

"E-Erm…" He cleared his throat. "It's… not very important. Just some silly things… You know… about change and all. I should play the refrain. To give you an idea." He said as he grabbed his guitar.

"Hum… It's not necessary, Juvia thinks."

Gajeel froze and narrowed his eyes.

"Why not? You like when I'm playing."

"Ah… Yeah… Sure…" Argh. She didn't know how Juvia could like Gajeel's songs!

He stared at her for some time and then shrugged and started to play. Lucy cringed a little but it was not as bad as she had thought. In fact, it was pretty nice.

"So what do you think?" He asked after the last notes.

"Yeah, it's good. It's a little different from your usual song but I like it. Now I'm gonna read your writing." She took the paper and began to read without noticing Gajeel's raised eyebrow.

It's a book tainted in red
The paper is brittle and the ink flowed
Your hands small and white
Gently flip the leaves

It will probably be a pain
And a time waste
But if you could rewrite my past
I'll offer you a new pen

At first Lucy was dumbfounded. She didn't expect that.

It was about his relationship with Levy, she realized suddenly. It was… so romantic! She didn't know Gajeel could be subtle and transcribe emotion with tenderness. He looked like a bad boy but in reality, he was a big softy. Now she understood his blush earlier. She smiled internally.

"It's… pretty good." She said finally, still a bit stunned but with sincerity. "We could work for some arrangement and we should think about a good phrase to end the song. But it's a good start."

She raised her head and met his scrutinizing gaze. Lucy struggled a bit under his stare. Did he notice something?

"What do you propose then?" He asked after a moment, his eyes still on her.

She smiled and took a pen. This mission promised to be fun. Writing was her domain after all.

###

The fight had ended some minutes ago, thanks to Erza, and the guild was quiet again as Gray and Natsu laid on the floor, both unconscious.

Juvia was still talking with her friends. They laughed and had fun. But for some minutes, Juvia was facing a problem. A delicate and intimate problem.

She needed to pee.

But it was Lucy's body and… well… it was embarrassing.

The pressure was growing in her belly. She couldn't wait longer.

She finally got up and excused herself. She went to the restroom and closed her eyes as she put her pants and panties down. After she had satisfied her needs, she felt better. It was still embarrassing though and she hoped she would not have to do that anymore.

When she got out of the restroom, she was surprised to see Gray leaning nonchalantly against the wall. He met her eyes and he smiled seductively.

"Hey, babe. Where have you been? Did you forget our date?"

Juvia felt a heavy weight in her stomach and something constricting her throat.

Babe? A date?

Lucy lied to her? How could she? She said she was Juvia's friend!

She was feeling cold everywhere. Her vision was blurred because of her tears but she saw Gray's eyes widening.

"Oh shit!" He hissed as he made a few steps towards her. "I'm sorry, Juvia. I was joking."

She felt a short relief with his words but soon…

Oh gods! He knew!

She couldn't breathe properly. He knew. He knew! Her legs were shaking as if they were made of jelly.

"Shit." Gray cursed once again and pushed her gently against the wall. "Breathe Juvia. Don't faint on me. I'm sorry. It was just a joke."

Juvia closed her eyes and forced herself to calm down and take a deep breath.

"It… It was a very bad joke, Gray-sama." She finally said with a hoarse voice.

"Yeah. Sorry." Gray admitted and scratched the back of his neck. "I just wanted to pay you back because you and Lucy think you could fool the all guild."

"It… It's not like this." She didn't want Gray thinking she was making fun of him. "Juvia asked Lucy-san to! It's all Juvia's fault and she's so embarrassed! Lucy-san was very nice and agreed to keep the secret!"

"Okay. Relax. I'm not angry at you or Lucy. But could you explain what happened to you?"

Juvia flushed red and ashamed she played with a strand of blond hair.

"Juvia took a potion last night. But she didn't know it would turn her into Lucy and Lucy into Juvia. Levy-san is analyzing it. Maybe she'll find some clue or an antidote and Juvia and Lucy-san will turn back."

"It's very odd." Gray stated and Juvia flinched a little. "Where is Lucy by the way?"

Of course he was worried for Lucy… Juvia shut down her jealous side.

"She's with Gajeel-kun. Juvia hopes everything went well."

###

Lucy and Gajeel had spend two hours and a half in putting down words, searching for rhymes, arguing about a metaphor, changing, erasing and moving phrases. But they finally ended with a complete song. They were a bit tired but Lucy was proud of her work and Gajeel seemed pleased with the result.

They came back to the guild for relax. As soon as they entered the hall, Lucy searched for her long blond hair. She hoped Juvia was fine without her.

"Thank you for your help." Gajeel said as he went to the bar. "See you later, Bunny girl."

"Humm…" She answered focused on her search for Juvia. "Goodbye Gajeel-kun!"

Where was Juvia? Did something bad happened while she was with Gajeel?

She suddenly froze.

He called her Bunny girl, didn't he? Not Sprinkler, the pet name he gave at Juvia. But her pet name.

Did he find out the truth? How?

She replayed the previous hours in her mind but was unable to remember if he said something or if he seemed to know that she was not Juvia.

Her thoughts were stopped as she saw Juvia walking towards her.

She was accompanied by Gray.

Lucy felt the usual wave compressing her chest and clenching her heart. But she managed to lighten it. Good. She seemed to handle it better. Earlier it was so intense, she had been unable to think properly.

"Hey Lucy." Gray said with a mocking smile.

Her eyes widened in surprise and she looked at Juvia for answers.

"He knows." Her friend stated simply but before Lucy could ask for more information, the blonde added, as if she was worried. "How was it with Gajeel-kun?"

"It was… quit entertaining really. But I think he has some doubts about us." Lucy replied.

"I guess you were not as good in your role as you think." Gray teased her and annoyed Lucy puffed on her blue bangs.

"I was perfectly into character."

Gray smirked.

"By the way, Gray-sama, how do you find out the truth?"

Gray seemed suddenly uncomfortable.

"Hum… well… I don't know… probably because of the way you act…" He eluded without looking at her.

Juvia was pretty sure he was lying. But she didn't want to push him. She knew he was a secretive person.

"Okay. It's too early but Juvia is going to see if Levy has found something nonetheless."

When she was further, Lucy who was not dupe either by Gray's answer turned her head toward him.

"So? How do you really find out the truth?"

"I don't know what you mean."

She stared at him intensely and he looked away, a drop of sweat rolling down on his temple.

"Okay…" He finally surrendered and answered with a flustered face. "It was because of the way she smiled at me when I handed her the orange juice. It was the 'Juvia's smile'."

"The Juvia's smile?"

If possible he seemed to be more uncomfortable.

"It's the name I found for the smile she gave me. Only me."

Lucy grinned.

He glanced at her and winced.

"Jeez… Don't smile like that. It's creepy."

"You liiiike her!" She teased him sounding like Happy.

"Would you shut up?" Gray whispered between clenched teeth as he saw Juvia coming back to them.

Lucy held back her giggle but when she saw Juvia's expression, her smile faded.

She was looking down and her face was livid.

"What Levy said? What's wrong?" Lucy urgently asked as soon as Juvia was near them.

Juvia raised her brown eyes, tears forming in the corners.

"She…She said the potion was a fake. It's just made of water, sugar and rose. Nothing magic."

It took some time for her words to sink into Lucy's mind.

"Wait…" She thought aloud. "Does that mean it's not the potion that responsible of the body's shift?"

Juvia nodded slowly.

"But…" Lucy gulped with difficulties. "What is the cause then? And… how can we turn back?"

At her question, Juvia muffled a sob.

"Juvia doesn't know."
