The final part to CLS :)

Curing Love Sickness
Inspired by the one-shot manga, Celeste Blue

"OH MY GOD! YOU'RE THE BEST, NATSU-SENSEI!" Mikan glomped Natsume which caused them both to collapse onto the ground in front of everyone, "I GOT AN 80 OUT OF 100 IN MATH!"

Natsume smiled slightly at the perky girl and patted her head. "Congratulations. Now could you maybe get off of me?"

Mikan became aware of the position they were in and blushed. She flusteredly stood up and grinned, "Three weeks of after school tutoring was what it cost and it was all worth it!" She beamed.

"Yeah," Natsume said absentmindedly while staring at the girl.

A rosey tint crawled up Mikan's cheeks as she recalled some things Koko had said to her at the Noriaki basketball game...

Flashback

"So has Natsume been treating you well these past couple of days?" Koko asked.

Mikan smiled. "Absolutely! I remember one time we were studying outside and it rained so he offered to continue the lesson at his home."

"Natsume offered?" Koko's eyes widened.

"I guess it was more liked forced..." She laughed, "But it was still really nice of him. I didn't know Natsume was that kind!"

Koko stifled a laugh. "Did you know that you're Natsume's first friend who's a girl?"

Mikan's eyes widened. "You're kidding!"

"I kid you not," Koko held his hands up with a chuckle. "He actually smiles more frequently now too. I swear I still can't get used to it but I like it more than that stoic block of wood expression he has on all the time."

"It IS like a block of wood, isn't it?" Mikan laughed.

"Right?" Koko guffawed, "It's so cute how he skips half of practice all the time to be with you!"

"He does?" Mikan's face heated up and somehow she felt like that information alone was all she needed to have a good day.

"Oops, said too much. Have fun cheering on Natsume, Mikan!" Koko waved to Mikan as he got up and headed to Narumi.

End of Flashback

Mikan shook her head. "Koko was probably exaggerating. He wouldn't take time from basketball to help me..." She thought.

"Are you okay?" Natsume asked as he put a hand to Mikan's forhead. Mikan blushed and inwardly reprimanded herself to stop it.

Natsume took his hand off, "No fever." He said.

"Because I'm perfectly fine. I passed math and I'm ready to take on the world." She gave him a thumbs-up.

"Not so fast there. Say that again when you get a perfect score." Natsume smirked.

"Let's celebrate, Natsume! For my newfound smartness!" Mikan cheered.

"You just completely ignored me with ease."

"Do you want to celebrate or not?"

"Fine. I have to take responsibility for my student's best score she ever achieved after all."

Mikan laughed and tugged on Natsume's hand.

Natsume briefly remembered that day Mikan heard about her childhood friend's break up with Imai, "It looks I don't need to know how to cure love sickness anymore, sensei!" was what she said.

"You don't need to know anymore but I probably do." He thought to himself.

"The amusement park?" Natsume quirked an elegant brow when he took one look around at where they were. Balloons, cotton candy, distant screams and laughing, and people in costumes crowded the walkways.

"Yeah!" Mikan smiled. "Koko gave me two coupons as a present of passing my first math test. He told me that you loved amusement parks, too!"

"Ugh," Natsume groaned. "That meddling bastard."

"Did somebody refer to me?" As if on queue, Koko bounded up out from in between them and put an arm over Mikan, the other on Natsume.

"Koko! What are you doing here?" Mikan asked.

"Came to check up on my best friend and my cute kouhai, of course!" Koko smirked.

"Mikan's in our year and in YOUR class for that matter." Natsume said.

"Whatever," Koko laughed. "She's adorable, she's tinier than me, and she's a few months younger than us. Therefore she is my kouhai."

Natsume rolled his eyes in annoyance and Koko started pushing the pair to a ride.

"Now have fun you kids! Papa's got do some business!" Koko grinned like a proud father and when the two were out of sight, he calmy said the word "Howalon."

At that, two boys jumped out of trees and two others climbed out of bushes.

"Wow, you're a genius, Koko! You got them to go out together." Tsubasa crossed his arms and smirked.

"May I just ask why 'howalon' is the code word to hide and appear?" Yuu pulled a twig out of his glasses and brushed dirt off his shoulder.

"No you may not." Koko held a hand out for Kaname to put binoculars in.

"Isn't it wrong for us to come here and stalk them?" Kaname asked.

"It's fine! If you want to go home, then go but just know that while you sit there all alone, you COULD be at the amusement park watching Natsume bend over backwards for Mikan." Koko shrugged.

"I hate it when you're condescending." Kaname frowned.

"So is he going to confess today?" Mochu asked.

"Who knows? By the looks of it, he's the type of guy to never do it unless she does it first." Koko looked through the binoculars and found his primary targets on the teacup ride (A/N: You all know this ride, right? ^_^). Natsume was keeping on a stoic front and spinning the wheel while Mikan tried her hardest to sit properly.

"But we're going to make sure that doesn't happen!" Tsubasa said triumphantly.

"That was killer, Natsume! I felt like my head untwisted itself off of my neck." Mikan mumbled.

"I didn't feel a thing." Natsume smirked.

Mikan glared at him. "Because you were the one spinning the wheel!"

Natsume wasn't paying attention anymore when he spotted a boy from afar. He was wearing a beanie with spikey hair poking out. "Hell no, it's Andou. So this is what Koko meant by 'business.' " He furrowed his brows.

"Let's ride that big one!" Mikan's eyes lit up and Natsume's attention turned back to her. She grabbed Natsume's hand. "Do you like rollercoasters, Natsume?"

"I've never ridden one before." He shrugged.

"What? That settles it! We're riding it and then I'll buy one of those photos they take when you ride them." Still holding onto his hand, Mikan quickened their pace and lined up.

"It looks like it will be about 10 to 15 minutes until our turn," Mikan pouted.

"I'll be right back," Natsume muttered as he caught Koko waving maniacly at him from behind a trash can.

"Caught his attention," Koko said.

"I thought the plan was to not let him notice us." Yuu sweatdropped.

"No, Iinchou. We want him to know we're here so that we can help him. At least that's what Koko told me." Mochu answered.

"Correct. We'll be like Natsume's fairy godfathers!" Koko grinned. "Here he comes!"

Natsume was not amused and his lips were set in a straight thin line. "You brought the team with you?"

"Only Tsubasa-senpai, Kaname-senpai, Mochu, and Iinchou." Koko answered, "We're here to help!" He explained.

"We think you have something really good going on here." Kaname smiled.

"Yeah, we're going to make this the best day of your life!" Tsubasa grinned.

"Thanks but no thanks. Can you just go home?" Natsume grunted.

"Sure... but just know that while we're sitting home alone, we COULD be here assisting you like the perfect non-biological brothers you've never had." Koko shrugged.

"That condescending shit doesn't work on me, Koko." Natsume crossed his arms.

"Damn. But that condescending shit worked on Kaname-senpai..." He muttered.

"Hey!" Kaname shouted.

"Everyone, shut up. Sakura-san is looking this way!" Mochu panicked and they all crowded behind several trash cans.

"Wait. Why am I hiding? I'm supposed to be out there." Natsume's lips thinned in a straight line and stood up.

"You better go back now. She's is at the front of the line," Yuu said.

"Just keep out of trouble." Natsume warned them as he headed back to Mikan.

"Do you need me to hold your hand, Natsume?" Mikan asked nervously as they were buckled securely into their seats.

"No." Natsume answered, "But it looks like you need it more than me." He watched Mikan shake in her seat and grasped her hand gently. He gave her a reassuring squeeze. Honestly, it looked more like Mikan's first time on a rollercoaster rather than Natsume's.

Mikan smiled at him for half a second before they launched straight across the tracks into screams.

"Thanks for holding my hand, Natsume." Mikan said as she inwardly blushed at the thought while they got off the car.

"Sure," Natsume said while he helped Mikan try to stand up properly.

"How did you manage to keep such a rock solid poker face on the entire time?" Mikan threw her hands up exasperated.

Natsume tried to stifle a laugh while he stared at the photograph that was taken. "You look like you're trying to give birth."

"Shut up," Mikan scowled. "I did say I would buy the photo to commerate your first time though."

Natsume gave her a tiny smile. "I'll buy one too."

The rest of the day went with Koko and the crew popping up behind Natsume every so often chanting "Kiss her! Kiss her! Kiss her!" and then making kissy faces behind his back.

"This is the last one and then the day can end happily!" Mikan chirped as they stood in line for the Ferris wheel.

Natsume nodded his head. "Are you thirsty?" He asked.

"Just a little." Mikan responded.

"Wait here. I'll buy you something to drink." He walked away to a food stand and asked the man there for a bottle of iced tea.

The man suddenly grabbed Natsume by the shoulders and grinned from ear to ear.

"What the hell?" Natsume furrowed his brows and tried to push the man's face away from him.

"Ow, ow, ow! Chill! It's Koko!" The man whined.

Natsume groaned. "How many times do I have to tell you and the guys to go home?"

Several guys with aprons and goofy mustaches popped up. "Hey Natsume," They said all together.

"Now listen to me," Koko grabbed Natsume by the shoulders again. "Now is the perfect opportunity to tell her. It's sunset and you'll be on a Ferris wheel at the top. I don't care how you do it but you should know by now that you won't move forward unless you do something."

"You're being dramatic." Natsume replied, face as stoic as ever. But somewhere there, Natsume knew Koko wasn't wrong.

"He's right, Hyuuga-san. If you don't ask, the answer will always be no." Yuu peeled off his mustache in irritation of its itching.

"Yeah. You don't want to remember Mikan-chan as the one that got away." Kaname smiled.

"You can smack us all you want but don't let telling her slip away, man!" Mochu grinned.

"I second all of what these dunces just said. Now take this bottle of ice tea and go kiss the shit out of her!" Tsubasa patted Natsume's back.

Natsume stared at each of their encouraging faces. "You guys really are like my non-biological brothers," He smirked.

"Save the bromance for later! Go now or else we'll wallop you for screwing up!" Koko grinned.

"Do you need me to hold your hand?" Natsume teased as they stepped into their gondola.

"I think I can handle a Ferris wheel." Mikan laughed and then paused to smile at him, "I had a good time, Natsume."

"Not the best day of your life?" Natsume smirked.

"The best day of my life hasn't happened yet. But I see it and I know what's going to happen it! I'm going to meet my soulmate, we'll get married, and have a happy family with all our close friends!" Mikan beamed.

"That sounds nice," Natsume genuinely smiled at that.

Mikan nodded and they both looked out the window. The orange and pink lit sun was half down at the skyline and looked like it was slowly but surely sinking into the lake that was next to the amusement park.

"It's beautiful." Mikan gushed.

"Yeah. It is," Natsume hesitated and remembered the words of his companions. "You're beautiful, too."

Mikan looked up at Natsume and blushed. Natsume stared back at her and gave her a knowing grin.

"Hey Mikan," He asked. "How do cure a love sickness?"

Mikan's eyes widened, "Natsume?"

And at the very moment, Natsume chose to do it.

He kissed her.

Natsume's self-promise to never fall in love gave way for something else. The promise to keep the sweet brunette: Mikan Sakura.

"How do you cure a love sickness?" Natsume repeated with a smirk.

Mikan laughed ⎯ still blushing with pink coated cheeks ⎯ and hugged Natsume.

"You don't." She answered with a smile.

The best day of both Mikan's and Natsume's lives had soon come true after Alice College had ended.

End of Part 3
and the end of Curing Love Sickness

I know I probably failed to show the development in Mikan's feelings for Natsume D:

Luckily the floor is open for your own imagination because I made the part about the rest of the day before the Ferris wheel brief! xD

Thanks again for reading and for all the reviews/faves/alerts!
