Summary: Feeling a bit down, Juvia took a potion that promise to change her. But she didn't expect to turn into someone else. Someone she knew very well. [Gruvia with a slight Nalu (and a bit of Navia?! ^^) ]

AN: I don't know if this idea was already used but it popped in my mind and I give it a try.

Someone else

Chapter 1: Wish

Juvia was very excited as she approached the guild.

Tonight shooting stars would be seen in the sky and she wanted to watch them with her Gray-sama. She hoped he would accept her invitation. This afternoon, she had prepared some food for a picnic and now she was carrying it in a basket.

A diner under the stars… How romantic!

She giggled. She shouldn't present it like this or Gray would say no in an instant.

She pushed the guild's doors open and searched for her beloved. But she couldn't find him.

"You're looking for Gray, Juvia-chan?" Mira asked from the bar.

Juvia came to her and nodded enthusiastically.

"There is a shooting stars shower tonight. He joined Lucy along with Natsu and Happy to see it."

So he went with Lucy…

Disappointment fell on Juvia and washed away her excitement.

"Juvia sees. Thank you Mira-san." She smiled to hide her deception and turned her heels.

"They're in the park if you want to join them!" Mira shouted behind her. Juvia didn't react and kept walking outside the guild.

But when she passed by the park, she hesitated for a moment before entering the park. There were families under trees and even some couples lying in the grass. Apparently, she wasn't the only one who heard about the shooting stars. After some minutes, she spotted her four friends seated on the ground. She didn't want to disturb them but she wanted to see the falling stars with Gray, she had to try at least.

With his dragon senses, Natsu was the first to notice her approach and smiled at her.

"Hey Juvia!" He greeted her and the others turned their head toward her.

"Good evening mina-san." Juvia said with a low voice.

"Good evening Juvia!" Lucy returned with a bright smile while Gray said a simple "Hi."

"Did you hear about the stars Juvia?" Happy asked.

"Yes. Juvia made some food for a picnic." She raised the basket for good measure.

"Great! I'm starving!" Natsu exclaimed and reached for the basket but Gray hit him behind his head.

"Moron! She didn't say it was for you! And you were eating at the guild some minutes ago!"

"You want a fight, icepants?"

"It's okay, Gray-sama." Juvia said before they punched each other face. "Juvia doesn't mind. We could all share."

"Ah! See, sloppy eyes?" Natsu grinned at his frenemy who just shrugged.

"Sit here, Juvia." Lucy patted a place beside her. "Don't mind the boys. You know how they are."

Natsu and Happy didn't waste time to stuff their head with food while Lucy asked Juvia about her day. They chatted casually for a moment, but the night fall rapidly on the park and excitation started to rise.

The Fairy Tail members scanned the sky, each of them hoping to be the first one to see a shooting star.

"Lucy! Look!" Gray exclaimed and touched Lucy's shoulder as he showed her a falling star, the trail of light tearing the darkness of the sky.

Juvia felt a lump in her throat with Gray's gesture.

"It's so beautiful." Lucy whispered and the ice mage hummed in agreement.

Juvia turned her gaze towards the sky. Usually she would jump up and scream "Love rival" at Lucy but now she was just feeling sad, as she was out of place.

She watched the sky but without enjoying the stars cracking the firmament. After a moment, she got up and excused herself, saying she was tired. Natsu made a panicked face, thinking she would take back the food, but she reassured him that he could keep it.

She left after saying goodbye to all of them and didn't notice Gray's eyes following her until she was out of sight. But Lucy did.

"If you want, you can walk her home, you know?" The blond said with a knowing smile.

"Shut up." He replied, a light pink rising on his cheeks. "Oi! Natsu! Give me a sandwich."

"There's no more left." The pink haired man said his mouth full of food.

"What? You ate them all?" The ice mage shouted angrily.

"You said you weren't hungry!" Natsu shouted back.

"No! I said you had already eaten at the guild! Idiot!"

And then they started to fight. Lucy sighed, knowing the peaceful show was ended.

Juvia closed the door of her apartment in Fairy Hills and went to her drawer to pick a change. Lost in her thought, she rummaged into her clothes and her fingers touched a hard and cold surface. A bit stunned, she picked out the strange thing. It was a vial with a purple liquid inside.

After some minutes of thought, she was practically certain it was a relic of her "potion phase" when she roamed all sort of markets searching for something able to make Gray love her.

She put it on her desk and went to her bathroom. After her shower, she sat on her bed and picked the vial to examine it more closely.

The potion was entitled "Be someone else" but there was not a leaflet on the bottle giving more information. So she presumed she had to drink it.

Becoming someone else.

She could take the risk. Maybe it could erase her default and turn her into someone Gray-sama would like.

Nothing would go wrong this time, after all she was the one to drink the potion.

Juvia made her mind up and closed her eyes, her hands pressed against her chest, enclosing the little bottle of glass.

She wanted to be more confident.

Like Lucy.

She wanted to be more joyful.

Like Lucy.

She wanted to be smarter.

Like Lucy.

She wanted to be more attractive.

Like Lucy.

The image of Lucy was very vivid in her mind. With her smile. Her long blond hair. Her laugh. Her confidence when she talked with Gray-sama.

A falling star split the sky.

Just one day. I wish to be her.

She opened her eyes and drunk the potion in one go.

Then she waited a little but she didn't feel any change inside her.

"Maybe it will take some time for the potion to make effect." Juvia whispered to herself before she sighed deeply. The potion was probably a scam. "Juvia was foolish. A potion can't change her."

She fell back on her bed, grabbed her Gray-sama plushie and turned off the light.

Maybe tomorrow, she would manage to invite Gray to share lunch. Only the two of them.

With this hope she closed her eyes and soon Juvia was sleeping.

###

The next morning, Juvia was awakened by a ray of light on her face.

She groaned without opening her eyes and turned on her side. She didn't want to wake up so soon. It was a bit strange because usually she was a morning bird. But right now, she was warm and her bed was very comfy.

She buried her head more into her pillow and moaned in contentment.

Then she felt a weight on her waist and she was pulled against a hard chest.

Heh?

She opened her eyes and met a muscled and naked man torso.

Okay. She was probably still dreaming.

A sexy dream with Gray-sama.

But something was strange, she thought with a frown, this chest was a bit different from Gray's torso. She had seen it a lot with his stripping habit and she had recorded his image in her mind.

She looked up and froze.

She was not in Gray-sama's arms.

The man who was deep asleep beside her was… Natsu!

"Kiyaaaaaaaaaaaaaa!" She screamed with horror and her scream woke the dragon slayer up abruptly and he fell off the bed.

"Ouch!" He moaned and rubbed his lower back.

"What is it?" Happy yawned, from the other end of the bed where he was laying. "It's too early for an argument."

"Wh… What are… you two… doing in m… my bed?" Juvia asked, stuttering because of her shock. Her voice was a bit different too.

"Come on, Lushyyy." Natsu said with a big yawn. " 's not the first time we sneak into your bed."

Oh.

Oh, gods…

She couldn't say anything as she watched the pink haired man stretching and getting up from the floor.

"Yoosh! If we are all awake, we should start with breakfast! I'm starving!"

"Yeah!" Happy agreed. "Can you make pancakes, Lucy?"

The two of them turned their head towards her with a bright smile on their face.

"O…Okay." She said uncomfortably. "Give Ju… Give me just some minutes." Juvia corrected herself and rushed towards the bathroom.

Lucy's bathroom.

She locked the door and breathed deeply.

Okay, she needed to calm down. It was probably a dream. It has to be a dream.

She went to the sink and plashed some water on her face.

She raised her head and her eyes met her reflection in the mirror.

Long blond hair was framing a bewildered face with brown eyes.

Oh, what she had done?

AN: Review will be extremely appreciated!

It's the first time I write something about Nalu, I'm more used with Gruvia, so any comment is welcome.

Oh, and I'm not an English speaker so please excuse my mistakes. But feel free to correct me (in a kindly way) :)
