AN: Hello everyone! I wanted to take the time to thank everyone who are reading my story. Are you ready for some GRUVIA?

Please let me know what you think :D

Gray Fullbuster has not had a good sleep since his future son appeared in Fairy Tail. He's seen a lot of crazy things happen but meeting Grant was in the same caliber of craziness as meeting Edolas Gray. For all of Gray's indifference, he'd be lying if he said he's not at all curious as to what the future is like.

Gray has reached the coffee shop and taken a seat in a spot he recently claimed as "his spot." He never really drank coffee but his lack of sleep required the caffeine and although Mirajane can easily make him a nice fresh cup for free, the ice mage did not feel like going to the guild lately.

Ever since Grant appeared, Gray has received a lot of questions about his love life.

As he took his first sip, he thought of some comments people have recently said.

"So Gray, does anyone strike your fancy right now? You must have some idea who the mother is." Mirajane tried to inquire with a wink.

"At least now you know your legacy will live on." Cana said, as if implying she never really thought he'd get a girl, let alone a family.

"Heh, your son is a lot nicer than you." Natsu provoked before their usual fights.

Gray sighed in his seat. "Everyone is so annoying lately!"

Just as he thought that, he realized that everyone has been annoying except for one person.

"Juvia, instead of wasting a seat there where another customer can use, why won't you just join me?" Gray said nonchalantly to the girl wearing a very lame disguise across from his table.

After so many months, Gray got used to Juvia's presence and wasn't at all bothered by her stalker ways. She never bothered him in anyway so Gray never thought the girl was a nuisance. Maybe at first it was awkward because Juvia would constantly stare at him but recently Gray noticed how Juvia seemed to just want to be in the same room as him. Like right now, Juvia is engrossed in a book, though she could read it somewhere else, he's not dense enough to not realize she's here because of him. Deep down inside, Gray felt the same way. He doesn't really want to be alone, contrary to popular belief; but at the same time, he does not like being bothered. As he thought this, he realized how Juvia is probably the only person he's comfortable being absolutely quiet with.

Juvia walked to where Gray sat very slowly. Once she was standing in front of him, she bowed her head and apologized. "Gray-sama, Juvia is very sorry. I didn't mean to cause inconvenience to you. It's just that you haven't been in the guild for a while and Juvia started to worry."

"Seriously Juvia, you worry too much. Just sit down and join me."

"Are you sure you want me to join you."

"I wouldn't ask if I felt otherwise." Gray replied with a small smirk.

Juvia sat down while wearing a bright red blush and Gray returned to drinking his coffee. Juvia was just as curious as the rest of the guild who Grant's mother was, maybe even more curious than everyone else combined, but her fears of finding out who the lucky girl is outweighed her curiosity.

"Either way, I'll be heartbroken. Why would I want to experience the pain so early on when I can spend a few more years just living in oblivion."

She tried to focus her attention back to the book she was reading.

"What are you reading, anyway?" Gray asked, sincerely curious as to what the blue haired girl is interested in.

"A book."

"Yes, I could see that. What is it about?"

"I haven't really read far to know, but Lucy lent it to me last week. She said I would love it. It seems that the genre is romance." Juvia explained.

"Hmm, Lucy sure is nice to lend her books like that. She really treasures novels so it's kind of a big deal when she lends them out."

Gray was happy for Juvia. She has made a lot of friends since joining Fairy Tail and it pleases him to see that she's opening up to more people aside from Gajeel. "She really does have a good heart," was all he could think of as he remembers how she was an enemy and now she's very well-liked by the other members, even Lucy trusts her, despite how Juvia tried to kidnap the celestial wizard in the beginning. A small smile played on Gray's lips as he looked outside the window.

Right across from him was a different sight. Juvia had a frown on her face and was green with envy. She has misinterpreted Gray's words and smile. "Love rival sure is hard to defeat. Gray-sama just praised Lucy's kindness." The more she thought about this, the more she believed that Lucy is Grant's mother.

"Grant is kind… Lucy is kind. Grant is caring, that's very apparent with how he acts toward Luna. Lucy is very caring too. Grant is strong too, I could tell. Lucy is… kind of strong. I'm still stronger but Gray can make up for both of them." She began to internally panic as she assumes that Lucy is Grant's mother. She instantly wanted to get amnesia. She liked Lucy as a person and would really rather not learn to hate the girl. She accepted that nothing will happen between Gray and herself. She truly believed that this acceptance will soon lead to her moving on and accepting Gray's soul mate as the one right for him. It was how she hoped things would play out. Right now, she wasn't ready finding out whom Gray will spend the rest of his life with happily. She wanted to cry and run away but at the same time, she knew something was bothering Gray and she cared more about Gray's well being than hers, so she decided to stay seated down and accompany the ice mage.

I'm so pathetic. Was all Juvia thought as she sighed.

"It's really bothering me," Gray started to speak, not quite sure why he's opening up to Juvia. "Why is he here?"

"You mean Grant?" Juvia asked.

"Yes, I just don't understand why he's here." Gray looked as though he was thinking really hard.

"Gray-sama, Grant explained to the guild that there's an enemy hiding in the past. That's why he's here."

"But why him? Why not Natsu's child? Or even Erza's? Or they could have sent future me, I'm sure I'd be stronger by then than I am now." Gray wasn't really sure why this bothered him so much but Juvia figured it out the moment he questioned why Grant was sent instead of others.

"Gray-sama seems to be very worried about his son despite only meeting him a few days ago." Juvia placed her book down and turned all her attention to the confused Gray.

"Wh-why would I be worried about him?!"

"Maybe it's just instincts. However way you look at it, he is your son and is a part of you no matter what time period it is. Don't you think that leaves a mark on your soul?"

Gray thought more of what Juvia has just said but after a pause, Juvia continued speaking.

"Although, truthfully speaking, I'm worried too. Maybe because he's your son and I know there's a part of you in him," Juvia's mind start to wander off as she spoke of words not meant to be said out loud. Her tears began to form as she continued, "How pathetic, I can't love Gray-sama this much that anything that has a part of him will affect me this much."

Gray didn't really know how to react. He's always known of Juvia's feelings but something with how she worries about Grant confirms her feelings for him to be real, something more than just puppy love or physical attraction. He finds comfort in this knowledge but he also worries about the girl. He spoke, despite himself.

"You know, it's not just Grant. Luna is worth the worry too."

"You're right, Gray-sama, but at least Luna has Grant to protect her. What about Grant? Who's going to protect him?"

"I have a feeling Grant is strong enough to not need protection." This didn't calm Juvia down, much to Gray's disappointed. "bu-but, if the time comes that he needs help, I'll protect him, at least while he's here." He really hoped this will calm Juvia down although, he wasn't very confident. Seeing as Juvia claimed to worry about Grant because he was his son. Gray wasn't really sure if putting himself in the frontlines with Grant will make Juvia less worried.

Much to his surprise, however, the water mage smiled and looked determined. "Juvia cares very much for Gray and his loved ones, so she'll protect him too. That's a promise. "

"You sure you wanna be making bold promises like that?"

"Yes, Juvia is sure." Juvia paused for a second and then corrected herself with more conviction. "No, I am very sure." Once in her life, Juvia was so sure with how she felt that she didn't feel the need to refer to herself in third person. As if speaking in first person held more commitment and responsibility. A commitment she wanted to fulfill.

Gray started to feel weird inside, in a good way. He was glad that someone was willing to share something as inconvenient as protecting a protector with him. Secretly, he began to really wish Juvia was Grant's mother. He pushed the thought away as soon as he realized what he was just thinking.

The two mages soon said their goodbyes as Juvia wanted to practice her water magic. Having a secret personal mission with Gray to protect Grant got her extremely motivated. Of course, she genuinely wanted to protect Grant as well.

When Juvia reached the guild, she noticed that Luna was with Lucy, Natsu, and Happy. "Luna, where's Grant?" the water mage interrupted the loud group.

Luna looked up to her Aunt Juvia, kind of surprised that she was looking for her friend. "He let me spend time with Natsu, Lucy, and Happy. He said that I could as long as it's in the guild. He's taking a nap somewhere."

"I see. I hope he's okay somewhere." Was all Juvia said as she walked away to look for Master Makarov and inquire on how to get stronger.

In the meantime, Gray found Grant napping under a tree by a river somewhere a bit farther away from the guild.

"Hey, is it really okay to be napping and being this far away from Luna? I can't have a slacker as a son." Gray started.

Grant sat up, surprised by Gray's words. His father has not at all acknowledged his presence ever since he introduced himself as his son.

"I'll sense danger when it comes. Right now, I want Luna to enjoy her time here even for just a little while. Besides, I'm confident Uncle Natsu will protect her."

"Hmp, well since you have spare time, come train with me then."

"Huh?" Grant felt nervous and excited at the same time. He has never trained with his father since he was always away. Although, Gray of the future is a lot stronger and wiser than the one in front of Grant, there is no way Grant will miss this chance.

Gray promised Juvia that he would protect Grant but he didn't want to be cheesy about it. Gray thought that training Grant and making sure he was strong enough is a way of protecting him as well.

Besides, Gray wanted answers and he's going to make sure to get them straight from Grant's mouth.

AN: It's going to be a busy weekend with my mom's bday coming up.

To apologize, here's some preview of what's going to happen in the future.

I can't really say that everything will happen in the next chapter, i try to limit my words to 2000 at a time .

Anyway! Preview time :D

BY THE RIVER

"So Grant, show me what you've got! Remember, for every hit I land on you, you have to answer one of my questions truthfully." Gray said, already feeling like he has won.

Grant knew this is bad, he was more used to water than ice magic but he's being forced to only use ice in this situation. His mind is so distracted that he didn't notice Gray's incoming attack.

"Point. Now tell me, why is your hair blue?"

GUILD HALL

"The more I look at them, the more I see the resemblance." Mirajane commented as she stares at Luna, Natsu, and Lucy.

"I agree. Luna's hair is as blonde as Lucy's." Levy said in agreement.

"Certain things make it possible for her to be Natsu's daughter too... like how she loves spicy food." Cana quickly added.

"Has anyone else noticed how she's always hungry? Almost as if nothing she eats satisfies her." Wendy said. Nobody really knew the relevance of Wendy's comment except Wendy herself.

"It would help if we knew what kind of magic she could do." Cana said, ignoring Wendy's words.

"Should we try to find out?" Mirajane suggested.

GUILD HALL (evening)

"Mira-nee, I'm back from my solo mission!" Lisanna said as she made herself comfortable in the bar area as she spoke with Mirajane.

"How was your mission?"

"It was very good. I came across someone, though, I'm not so sure you want to hear who."

"Spill it!" Of course Mirajane was curious now.

"Laxus. I know he's been exiled from Fairy Tail but when I saw him, he wasn't mean or anything. He was surprised to see me alive, actually."

"Really? the world sure is small for such a coincidence."

"I know right, he seems stronger now too. He said that he could control time now, thanks to an ally he made. Although, I think he's bluffing."

Without really thinking about it, Mirajane decided to find Laxus. This whole situation can't be coincidence. It's either planned by someone or fate.

LAXUS' OFFICE

"You mean to tell me that you sent my 16-year-old daughter to the past to fight Andre?" Natsu questioned furiously to the blonde guild master.

"Simply put, yes."

"ARE YOU ABSOLUTELY INSANE? You may be the guild master but you don't have the right to be deciding her life like that!"

"And you do?" Laxus responded back. "Natsu, your daughter is 16-years-old, when you were 16, you were handling missions on your own. She's part of the Prodigy team but as time progress, she's slowly becoming Fairy Tails most useless member. Besides, she decided to go on her own, I simply approved her request."

"I'm sorry, did you just call my daughter useless?"

SOMEWHERE IN FUTURE MAGNOLIA

"Jer, what do you mean she got burnt fighting Igneel?" Lucy asked the Prodigy team member.

"Uhm, well, isn't that what she does with her other dragon spirits?"

"Are you saying that she tried to make a contract with Igneel?" Lucy was frantic.

SOMEWHERE IN PAST MAGNOLIA

"Lucy, I love you."
