OTP challenge Gruvia

Chapter 1, At an aquarium

Gray Fullbuster was standing in front of the entrance of Fiores biggest aquarium. Next to him stood Juvia Lockser, who asked him on a date.

"I can't believe I actually did this." Gray thought. "Why did I got on a date with her?!"

Something was bothering Gray. Juvia noticed. "Is everything alright, Gray-sama?" Juvia asked.
"Yeah, I'm fine." Gray responded. He didn't want to be in a stupid aquarium and he didn't want to be there with Juvia. Not today. Natsu was going to fight Erza. Gray didn't want to miss that! He wanted to see flame-brain getting defeated by Erza, but suddenly Juvia asked him to go to an aquarium. Gray couldn't refuse. Juvia would've cried if he did, so he decided to come along.

"Juvia?" Gray carefully asked.
"What is it, Gray-sama?" Juvia curiously looked at Gray
"Is it okay if we visit all the fishes quickly and then leave?"
"Yeah, but why?" Juvia sounded a little disappointed. She also looked a little bit sad.
"Well, you know..." Gray had trouble with telling Juvia. "Pyro and Erza are gonna fight each other today and I don't wanna miss it!"
"Oh, Juvia understands." Juvia smiled even though Gray saw it was a fake one.

"I'm sorry Juvia."
"Is it because Love riv-, I mean Lucy is there too?"
"What, Lucy? Why would I go there for her? I wanna see Natsu's guts get kicked out!"
"Juvia sees..."
"You can come along if you want to."
Juvia smiled, this time for real, and screamed "JUVIA WOULD LOVE TO GRAYY-SAMAAA!! KYAAA~"

"That's the Juvia I know." Gray thought and he smiled too. Maybe this wasn't so bad after all.

Gray and Juvia were standing in front of a huge fish tank.

"Wow, look Gray-sama, there are so many colourful fishes!" Juvia pointed at a fish with a blue tail.
Gray just nodded, he didn't really know what to say. Sometimes Juvia acted like a 4 year old.

Next was a tank with gray coloured fish.
"This reminds me of Happy's lunch." Gray said.
Juvia laughed and said back "They remind Juvia of Gray-sama, the fishes are gray just like Gray-sama's name!"
"Err, thanks?" Although Gray found it creepy, he started to blush. He quickly hide his face in his t-shirt.

Finally they arrived at an arc with sharkes, turtles and stingrays swimming above them. Juvia grabbed Gray's hand. Together they walked through the arc of water. The exit was nearby, so Juvia shared: "It was really fun today, Gray-sama."
"Gray thinks so too. Damnit Juvia, now I am going to talk like you."
"Is that bad?" Juvia asked Gray kind of offended.
"Well, just a bit." Gray responded.
"Juvia is sorry then." Juvia apologised.
Gray smiled and told Juvia that it was alright. After that Juvia hugged him and they both blushed.

Once Gray and Juvia were outside, Gray said: "Quick, otherwise we'll miss the fight!"
"That's right! Juvia almost forgot."

After 30 minutes, Gray and Juvia arrived at the guildhall. Gray asked himself if he made it in time, but when he saw a big crowd he knew he wasn't going to miss the fight.

"I am gonna beat you Erza!" Natsu yelled.
"If I were you, I wouldn't be so sure of that." Erza calmly said.

"Be careful Natsu!" Lucy screamed.
"This is gonna be epic!" Gray mumbled.

"Fire dragon wing att-" Before Natsu could end his sentence, Erza had already take him down.

"I told you I was going to win." Erza said to Natsu who was laying on the floor. "Next time think before you pick a fight with me."
"Yes ma'am." Natsu could barely speak.

Gray becan to laugh.
"SHUT UP ELSA!" Natsu told Gray angrily.
"I can't help it, this was just so pathetic!" Gray was still laughing.
"You want me to fight you?" Natsu asked Gray.
"BRING IT FLAME-BRAIN!"

Before anyone could do something Natsu was laying on the ground again.

"Water Nebula."

Natsu was taking out by Juvia this time. Gray stared open-mouthed at Juvia.

"Juvia..." he said.
"Yes, Gray-sama?"
"HAHAHA you took out Natsu by just one go! HAHAHA. You're amazing."
Juvia couldn't stop smiling "You too Gray-sama."
Natsu was yelling: "I wasn't concentrating!"

Gray walked Juvia home that evening.
"Thank you for today Juvia. It was really fun."
"No problem Gray-sama. EVERYTHING for you."
"Well I must go now Juvia. Goodnight." After that, Gray walked home.

I know, this part is kinda deviated from the challenge. It was fun to write tho. I hope you did enjoy it!
