Hello everyone. I must say, this isn’t my first fanfic, but it will be my first time writing for any fandom that 4kids hasn’t mutilated. It’s been two whole years, so excuse me if I’m a little rusty to start off with. If you like my work or have any creative criticism (or spelling errors to report) then please review and tell me.

Summary: When Ryuichi was seventeen, he met Tatsuha, a cute two year old that became his first fan. Now, at thirty-one, he is in disguise and in Tatsuha’s care for a week. Getting a private look into the fan boy’s life, Ryuichi is slowly falling in love with him.

Rating: M (For later chapters)

Pairing: Tatsuha/Ryuichi (And some other Gravitation couples we all know and love)

Disclaimer: I don’t own Gravitation. If I did, Ryuichi would be in every episode.

Warnings: This story contains Shonen-ai and Yaoi, and I wait for the day when this will no longer need to be a warning. -_- Oh, and Tohma is in here as well. Now that’s a warning!

By the way, Tatsuha and Ryuichi haven’t met in the anime, but in the Gravitation Ex manga, their relationship seems to be developing. So I won’t invade cannon and just say that this story will be taking place in the anime-verse.

Enjoy the first chapter. ^-^

Wanting the Best of Both Worlds

Chapter 1: Nanny Ryuichi

In a small suburban house on a particularly hot summer’s day, a teenage Tohma Seguchi was loosing his mind. Today was the day of the annual Seguchi family reunion, and the day he had chosen for introducing Mika Uesugi as his girlfriend and future wife. However, the entire preparation for the party had seemed to have gone to hell in a hand basket. Mika had been saddled with her baby brother that day – two years old and drooling like a fountain – and given that the girl couldn’t cook and look after the kid at the same time, and that Tohma was an utter failure at both, it didn’t take long for the intricately planned party to evolve into an all out disaster. Mika had burnt the roast, Tohma had broken a few glasses in the rush, and now the baby had thrown up on his new outfit and there was no one with a spare hand to tend to him.

“Alright,” Mika said, glancing at the charcoaled lump in the oven that was once a turkey, “I’m ordering pizza.”

Tohma sighed, replacing the fire extinguisher in its rightful place. If the coal-like appearance of the turkey wasn’t enough to turn one’s stomach than the suds covering it –not to mention half the kitchen – certainly would. “We can’t do that, and you know it. My family are all sticklers for class.”

Mika sighed, “I could get the second roast going, but you need to take care of Tatsuha if you want it to be ready in time.”

The sheer horror with which Tohma looked at the baby almost made Mika laugh.

“Hey Tohma – whoa!” Ryuichi Sakuma stopped dead in his tracks, taking in the mess in the kitchen: broken glass, suds everywhere along the counter and oven while thin tendrils of smoke rose from said oven. Tohma’s tie was loosened and his best dress shirt had patches of sweat showing under the arms and on his chest while he had one hand on a broom. Mika seemed no better off, her hair done up in a half hazard ponytail and her clothes crumpled and singed, probably from the – obviously recent – fire. Both seemed to be looking at Ryuichi with a sort of renewed hope in their eyes, and Ryuichi had no time to react before he had his arms filled with a giggling baby brunet.

At seventeen years of age, Ryuichi was as obsessed with music as Tohma was. They had even started a band the previous year when Tohma had found some half finished lyrics on Ryuichi's school desk and appeared the following day with a tune to match on his synthesizer. The two boys had had dreams of making it big ever since, entering talent shows and playing at local parties to increase their reputation.

Sighing, he dumped the toddler’s soiled clothes into the wash basket and went to check on how the energetic little kid was fairing in the bath. God willing, he hadn’t drowned yet…

Nope. Still alive. Tatsuha was splashing about contently, only quieting when Ryuichi's phone let out a happy jingle. Large, dark eyes watched the elder male as he perched himself on the edge of the tub with a “Hey, talk to me.”

The conversation evolved from there, Ryuichi none the wiser about the toddler’s close inspection of him all the while. Like most children, Tatsuha Uesugi was inquisitive and drawn to beautiful things, and he found Ryuichi to be a very beautiful thing. The teenager’s light brown hair fluttered about his face with every minute movement and his blue eyes almost sparkled with mirth at whatever the person on the other end of the line was saying. Tatsuha looked down at the pink plush bunny cuddled against Ryuichi’s chest and reached out a pudgy hand to bat at it.

“Okay, see you Sunday then,” Ryuichi said, snapping his phone shut and shoving it in his pocket so that he could get the child out of the bath when he noticed Tatsuha’s new fixation.

“Oh, you like Kumagoro, do you? K gave him to me yesterday.” He picked the bunny up under its arms and made it give a sloppy bow. Tatsuha gave a few wide claps in response.

“Hey, what do you know,” Ryuichi said, scooping the boy up in a towel, “My first fan.”

Ryuichi was almost finished dressing the baby when a haggard looking Tohma entered the bathroom.

“Mika is driving me crazy with all her worrying over the baby,” he said with a scowl. Then a surprised look crossed his face, “You’re already done? Mika said she had trouble bathing him on good days.”

Ryuichi smiled. “Maybe I’m just good with kids.”

“Maybe,” Tohma said, only relaxing when they were sitting on the sofa.

The tired blond lay his head on the boy’s shoulder with a massive sigh as Tatsuha crawled around on the floor at their feet.

“This entire day has taught me to always be one step ahead of everyone else,” he said. “From now on, I vow to never be caught by surprise again.”

Ryuichi laughed, “I’m almost scared now Tohma. You’re focused enough as it is, na no da!”

“Na…no... da!” Tatsuha said from the floor and Ryuichi’s eyes lit up while Tohma blinked confusedly.

“Aw, Tohma!” Ryuichi scooped the baby up, twirling him around, “He’s so cute! Come here Tatsuha, can you say ‘Ryuichi’?”

While Tatsuha struggled with the name, Tohma looked on in awe. Tatsuha was a difficult child, if what Mika said was true, and the kid was all but setting fire to the drapes earlier. But he was near angelic now… Was it all because of Ryuichi?

The doorbell rang and Tohma bolted up from the couch, “Oh for the love of – They’re an hour early!” He cursed, straightening his tie out of habit, then he glanced down at himself and Ryuichi giggled.

“Would you like me to be your nanny and doorman for tonight, Tohma?” He asked with a smirk.

“You don’t exactly look the part,” the blond said. It was true. Wearing worn sneakers, faded and ripped jeans and a thin black muscle shirt, the blue eyed teen didn’t exactly look in a condition to attend any kind of fancy social gathering. His many bangles, studded belt and spiked wristbands only added to his delinquent appearance.

“My clothes are at least more intact,” Ryuichi quipped, adjusting Tatsuha in his arms. “And it’s better than having a hole burnt in the seat of my pants.”

For the sake of his pride, Tohma really hoped his friend was joking as he headed for the stairs.

With that argument settled, Ryuichi scooped Kumagoro up in his other arm and headed off to the lion’s den while his best friend changed into something more decent. The last thought the soon to be singer had, before he was mobbed by screaming fat ladies and doting old men, was that the kid he held was sure heavy and was probably going to grow up to be a hell of a lot stronger than him.

It was a good fifteen years or so later that Ryuichi Sakuma, now thirty-one years of age and idolised by millions of fans worldwide, found himself standing outside the door to Tohma’s mansion on a summer’s night, carrying Kumagoro…

… and wearing a wig.

Ryuichi sighed. The wig wasn’t the worst part of his disguise, but he supposed the whole look was necessary if Tohma was going to keep him safe. There had been an attempt on the J-rock star’s life at his concert yesterday, and the fact that the group who had tried it had gotten away put everyone ill at ease that they would try again.

The blond keyboardist had said Ryuichi was to stay out of the public eye for a week until his next concert, until the ‘music hating thugs’ – as Noriko had dubbed them – were caught. Of course, Ryuichi, being Ryuichi, wasn’t planning to spend the entire time holed up in his apartment, so Tohma had promised him a week Kyoto, sort of a mini vacation, if he followed a few basic rules.

Rule number one was that Ryuichi had to be in disguise at all times, and since any person with even a general taste in music knew what the Ryuichi Sakuma looked like, the best bet was to go with something that, while suss, could be explained well enough to sound legitimate.

The door opened and Tohma smiled apologetically at the man while he took his luggage.

Ryuichi sighed, kicking the door closed and adjusting his skirt. Sure the skirt was just for show, tight and short with a pair of stylish jeans underneath, but that didn’t make dressing like a girl any less uncomfortable, especially since he had to wear a bra too, filled with falsies, under all his tops. The wig he wore was even the same colour as his own hair, reaching down to the middle of his back when not tied back. How this uncannily thin disguise was going to fool anyone more than a huge Kumagoro suit would have, the singer didn’t know.

“Oh, that’s right,” Tohma said suddenly, holding out a hand. Ryuichi pouted stubbornly, clutching his bunny to his chest protectively before finally handing him over. Tohma unceremoniously stuffed the poor thing head first into one of Ryuichi’s suitcases.

Rule number two: Kumagoro was to remain out of sight at all times.

“Now,” Tohma said, “I’ve asked Tatsuha to wait in the kitchen while I get you. You’re taking my car and you’ll be staying at his family shrine. I’m sure he won’t barge into you’re room since he’ll believe you’re a female. Just make sure to be up and ready before him in the morning and –”

“Tohma,” the singer interrupted, chuckling, “You sound like an overprotective mother.” Then he blinked, smiling, “Hey! You said Tatsuha! You’re not talking about my first fan, are you?” Ryuichi looked toward the kitchen now like it held gold, or better, candy. Was he really going to see that cute little baby again?

Ryuichi dashed off towards the kitchen.

“Wait, stop!” Tohma called, “He’s not a kid anymore!”

Ryuichi was almost giddy with excitement. Of course he knew that all babies grew up. How silly did Tohma think he was? Ryuichi quickened his pace. How long had it been since he’d last seen Tatsuha? How old was he now? Ten? Eleven? Would he remember Ryuichi? Would he remember he was Ryuichi’s first fan?

The singer burst through the shuttered kitchen doors with a wide grin and open arms. “Tatsuha! I missed you! Come here and give Ryu a big hug!”

Then Ryuichi stopped dead in his tracks.

Sitting on a stool, leaning over the counter, a piece of toast half way to his mouth, walkman in his ears, and reading the cover of the latest Nittle Grasper album, was a teenager. He was tall, and almost identical to Shuichi’s lover in appearance, except for his black hair and those eyes… The darkest, most entrancing eyes Ryuichi had ever seen.

The boy’s mouth was slack, eyes wide in shock and awe.

“Holy shit,” he breathed, the toast falling from numb fingers.
