The Date

Natsu heard the voice, his face overtaken by terror as he turned his head towards the door. Sure enough there was Erza, clad in her Heart Kreuz armor, standing in the doorway. He tried to hide behind the bar, but Erza had already spotted him.
She walked over to the bar and pulled him up from his collar, he had forgotten how strong she was. She looked him in the face and gave him an uncomfortable smile.
"Come on Natsu, it'll be fun."
She then proceeded to drag him across the floor of the guild hall as she headed towards the exit.
"Have fun you two!" Mira yelled as she waved from the bar ignoring the terror on Natsu's face.
Natsu could barely hear her from the sound of his heart beating out of his chest. As he continued to be dragged across the floor towards the door, he could hear his friend's laughter and mocking.
"Good luck Natsu!"
"It was nice knowing ya."
"Try not to hurt him too much Erza."
Natsu began struggling violently while in Erza's grip, his fear overtaking him.
"No! I don't wanna go! I changed my mind Erza let me go!" He then looked at his guild mates, "Guys help me! Elfman, Wendy, Gray, Lucy, Happy someone help m-"
Suddenly, Natsu's protesting had stopped and everyone laughed nervously once they noticed that Erza had struck him in the head with a strong fist. He remained unconscious until they exited the guild.
Natsu awakened a few minutes later. He slowly opened his eyes, the sunlight seeping through the leaves and branches of a nearby tree and into his eyes.
He looked to his left and saw Erza's armor close to his head. He was laying on her lap.
"E...Erza? What happened?" He asked confused as he sat up.
"You were struggling and making too much noise so I hit you in the head to shut you up. When you didn't wake up after we exited the guildhall I decided to watch you-" Her eyes widened and her face grew red in embarrassment. "I mean decided to wait until you woke up." She said catching herself. "Is that a problem?" Her eyes grew stern.
"Oh uh, no." Natsu began rubbing his throbbing head. "You didn't have to hit me so hard though."
"Stop complaining." She rose from the ground and patted herself off.
"Shall we go then?" She asked looking at Natsu.
"Where are we going?" Natsu asked standing up next to her.
"I have prepared a picnic for us."
"Really?!" Natsu smiled wide as he began to drool at the prospect of food. "Awesome, let's go."
He grabbed her hand, which made Erza blush slightly, and began to run, then stopped after running about 20 feet.
He then let go of Erza's hand and looked at her up and down.
"W...what is it?" She asked nervously.
"Are you really going to wear that thing on a picnic?" He asked pointing at her armor.
Erza looked down at her clothes confused. "Oh, yes I almost forgot I was still wearing this. Hold on I'll change. I brought an outfit just for today."
She stepped back from Natsu and began to glow a bright yellow, bright like the sun to be exact.
Re-Quip
She glowed even brighter as she was overtaken by magical power, which transformed her armor into something more appropriate for the day ahead.
Natsu covered his eyes from the brightness, but when he looked back he couldn't believe what he was seeing.
Erza, who rarely disrobed from her Heart Kreuz armor unless it was time for battle, was now adorned in a flowing white sun dress which stopped just above her ankles. Her brown boots had been replaced with wedged sandals and placed on random parts of the sundress were a pattern of scarlet roses which made her long red hair, which was now tied at the end, stand out more vibrantly.
When Natsu looked up at the top of the supposed stranger's head, he saw a tan colored sun hat with a black ribbon tied in a bow around it.
Natsu was taken aback at the sudden shift in his friend's appearance, he didn't know what to say. He was speechless, which never happens with him, but one thing was for sure; Erza in this moment looked...
"Beautiful." He said under his breath without realizing it.
Erza caught the faint noise from Natsu's mouth and blushed. "What...what did you say?"
Surprised, Natsu replied quickly. "It...it was nothing. Ready to go?"
Erza smiled softly at him. "Yes. Let's go." She grabbed his hand and the two began to walk to where Erza had set up the picnic basket.
After walking for a few minutes the two found themselves in a huge, green field on the outskirts of Magnolia. Next to a large tree that seemed to endlessly stretch into the sky, was their picnic basket. Natsu, seeing the basket, eagerly ran ahead literally salivating at the thought of food.
"Natsu, wait!" Erza yelled as she watched him run off, reaching out her hand. However as she watched him run towards the tree she couldn't help but smile. Even if a bit naive, she always admired Natsu's straightforward & innocent nature. She gripped the hand that Natsu had held onto earlier, and ran after him.
Erza arrived at the tree and saw Natsu sitting there quietly waiting for her. 
"What's wrong?" She inquired.
"Huh? Oh, nothing. I just thought it would be wrong to start without ya." He smiled wide showing his white teeth. Erza once again smiled and knelled next to the basket.
"Alright, alright I've kept you waiting long enough. Let's eat."
She opened the picnic basket, and Natsu sat on edge growing more and more anxious as she pulled the food inside out. Noodles that glistened like gold, pure white rice & piles upon piles of meat. Natsu's drool was literally drenching his shirt. Seeing this, Erza began to giggle at the Dragon Slayer. Natsu then looked at her, as if asking for permission to accept this wondrous bounty.
"It's okay, you can eat." She said smiling warmly.
So happy that he was given the okay, Natsu didn't waste a moment as he started to ingest the food like a wild animal. Seeing him so happy about her food made Erza giggle a bit more. Noticing this Natsu looked up from stuffing his face.
"What's so funny, Erza?" He asked.
"It's nothing, keep eating." 
"You're not going to eat?"
"No, I'm fine." She replied, reaching her hand towards Natsu and wiping a piece of meat off of his messy face.
"Oh, um okay." Natsu said blushing as her soft hand rubbed across his face. He then continued to eat. Erza contently watching him.
After a few more minutes, Natsu happily laid down in the grass while rubbing his stomach. 
"Man that was good, thanks for the food Erza." He said smiling at her.
Erza blushed hearing this, no one had ever thanked her for making food for them before, probably because Natsu was the only person she had ever cooked for. It felt...nice, especially coming from him.
"You don't have to thank me. I'm just glad you liked it." She smiled at him warmly, catching Natsu off guard he'd never seen this side of Erza before.
After a moment of silence, Erza spoke up.
"Natsu?"
"Yeah?"
"Do you...have feelings for anyone in the guild?"
Natsu looked at her confused. "Feelings?"
"You know..." Erza started to fidget a bit. "Do you like anyone in the guild?"
"Sure I do, I like everyone. I mean that's what friends do right?"
Erza giggled at his innocence, "No, that's not what I meant. I mean is there anyone in the guild you like more than anyone else?"
There was an awkward silence after Erza asked this question, making her feel a bit uneasy like she had misspoke. Just then Natsu answered.
"Well...I don't know ha ha." He said as he smiled and scratched the back of his head.
Erza fell over in astonishment. 
'How naive could he be?' Erza thought to herself as Natsu continued to talk.
"I mean I care about EVERYONE in Fairy Tail, but there are a few people I connect with more than others in the guild I guess. Happy of course, Lucy, Mira, Lisanna, Elfman, Wendy, the master, those jerks Gray & Gajeel; and...you."
When she heard that she was one of those people, Erza's heart skipped a beat.
"I guess because of all the battles and missions we've gone on as a team. I really couldn't imagine life in Fairy Tail without any of you guys." He sat up and looked towards the horizon, the wind blowing across the meadow. "I don't want to imagine a life like that." Erza could do nothing but stare at Natsu, she had never heard him sound so...mature before, so adult. It had a warming, calming effect on her that she couldn't hide and she smiled.
Without really being in control of her body, she reached out to him and grabbed his shoulders, pulling him down towards her.
"Wait Erza! What are you doing?" The startled Dragon Slayer asked. He closed his eyes in anticipation, thinking he was going to hit the ground hard; but this was not the case.
He opened his eyes and looked up, seeing Erza's looking down at him. She smiled as she rubbed the side of his face with her palm. Natsu really didn't know what to say, the light shining brilliantly from her face, making her look almost angelic.
"Don't move." She said as she looked towards the horizon, placing her hands on his chest. "Let's just stay like this for a little bit...please."
Natsu had no protests. He didn't know why, but he wanted to stay like this for a bit as well. Something about the warmth of Erza's lap felt nice to him. Erza seemed like a totally different person today it was refreshing, but Natsu had to be sure how to proceed next.
"Erza?" He asked with a determined look in his eyes.
"Yes, Natsu?" She looked down at him smiling.
"...fight me."
A surprised look appeared on Erza's face as she questioned him, "What?"
"Fight me." He said it a bit more forceful this time, "I gotta figure something out."
Initially, she was hesitant, she feared that if she beat him, their moment would be gone; but seeing the fire in his eyes caused her to relent.
"Alright, fine."
They stood up and walked south of the tree to a more cleared area. They stood opposite each other and Natsu took off his shirt, not wanting to ruin it.
Erza began to glow yellow again.
Re-Quip
When the light faded, she was no longer wearing her dress nor her hat. These things had been replaced by an orange, black & dark red breastplate. Greaves reminiscent of dragon's claws, orange gauntlets with claws, a pair of what looked to be dragon's wings and her hair was now tied into twin high ponytails. Finally she carried a long red sword in her right hand.
Natsu smiled as he saw the warrior standing in front of him, he knew the look of her Flame Empress armor anywhere and he knew that he would have a hard time beating her; but he wasn't trying to win. He wanted to clear his mind and the only way he could do that was by fighting her.
"You ready Erza? I won't go easy on you just because you fed me." Natsu smirked as he got into his battle stance his fists being enveloped in flames.
Erza smirked as well, as she got into her battle stance, sword at the ready.
"Raahhhhh!" Natsu ran at Erza with a ferocity all his own, and the battle started.
A flurry of flames decorated the sky as the two bounced off one another, but the flames weren't hot, they were warm...so warm that when they fell to the ground the grass glistened.
Erza noticed this and smiled, she had begun to understand what Natsu was trying to say to her. She had gotten her answer the only way he knew how to give it, through battle.
'Natsu, I see now. You were listening to me earlier, and I guess this is the only way you can make things clearer for me.' 
After an hour or so she beat Natsu and tossed him back towards the tree.
She changed back into her dress and walked towards him.
"Aw man, I almost had you that time." He said smiling.
"I know you did." She said as she pulled his head into her lap again. She then looked towards the setting sun, her face softening. "One day, you will surpass me. I just hope you will allow me to watch...and be by your side." She looked a bit sullen as day turned to night but something in the air caught her eye.
It was a heart, made of pure flame. She reached out and touched it, it was warm and she could feel that warmth throughout her entire body. She then looked down at Natsu who was just innocently smiling back at her.
As the crickets chirped in the field, Erza found herself moving her face closer to Natsu's.
Natsu blew some more fire around them lighting up the scene.
Erza's lips reached Natsu's and she could feel the warmth of his lips as they touched.
With the light of Natsu's warm flames illuminating them in the night, Natsu Dragneel & Erza Scarlet became one, through a single yet passionate kiss.
