Oki: Another short one-shot! *winks$

Yama:We dont; own KHR...

Oki: Enjoy and do review plz! .

Tsuna, the Vongola Decimo, sighed as he took a sip of his coffee, finally done with his paperwork. It had been several years since he took up the position of being Vongola's boss and every day the brunette faced was all mainly male mafiaso.

It was as if he was planning to be single for his whole life.

"You know, Reborn…" Tsuna was cut off when the door burst open and a purple bazooka flew in suddenly and landed right onto Tsuna. Before the brown-haired man or Reborn could react, pink smoke filled the whole room.

"I'm sorry boss; the ten-year bazooka flew in here…" Gokudera rushed into Tsuna's office minutes later, his eyes full of frantic. Yet, the storm guardian could not see his boss anywhere, and when the smoke cleared, all he saw was a shorter teen.

"Hiii, where am I?" a young teenager with brown-haired exclaimed in fear as he glanced around wildly, a little confused.

"You got hit by the ten-year bazooka, Dame-Tsuna." Reborn smirked, his gun aimed at the younger version of the Vongola boss. To be honest, Reborn was a little amused by the current situation. He was curious what his older student wanted to say about him being single, but another interesting thing happened first.

"You are now the Vongola Decimo, you know." Reborn continued leisurely, his eyes glinted with mischief, certain of his student's reaction.

"Hiii, I don't want to be the boss!" Tsuna slapped his hands to his face in horror and ran out of the office, leaving the smirking Reborn and a still stunned Gokudera in the office.

"Wait, boss, you will get lost!" Gokudera realized, immediately running after Tsuna, fearing that something bad would happen to the brunette.

"You know, this few days have been peaceful, I'm a little worried." Lee started, as he and his fellow mafiaso were walking along the corridor. They were currently on duty, patrolling the silent corridors.

Many interesting and disturbing things had happened in the past (due to him), yet it had been unusually quiet recently. Lee was worried.

"What do you mean?"

"I mean, doesn't it feel strange that it is so peaceful and quiet in Vongola? Normally it is noisier and full of explosions and shouting around the Decimo's office." Lee slowly expressed his thoughts, his face serious.

Pausing for a while, the mafiaso continued, his tone softer.

"I fear something major happened and we don't know about it." Lee nodded to his companions, certain of his deductions.

Right after Lee ended his sentence, a brown-haired teenager came dashing into him and the both of them hit the carpeted ground.

"I'm sorry!" Tsuna cried as he scrambled to his feet and bowed deeply. He was lost and started panicking, resulting in him running blinding through turns and corridors.

Tsuna slowly glanced up and gulped when he saw a fierce-looking mafiaso. Oh, he was so dead…

"It's alright!" Lee smiled warmly as he took a closer look at the teenager in front of him. He was quite sure he had not seen this kid anywhere in the Vongola HQ…

It was then Lee saw the resemblance.

He saw the resemblance between the brunette before him and his current boss.

Then it struck him.

"Your surname is Sawada, right?" Lee exclaimed in awe, not believing his eyes. He had to confirm it; he had to confirm that the boy was indeed his boss's son.

"How do you know?" Tsuna's eyes widened as he cautiously asked, a little surprised by the unexpected question.

Lee cheered inwardly as he turned to his fellow hit men and pointed to Tsuna.

"He is indeed boss's son! Why didn't the Decimo tell us that he had a child?" Lee whispered harshly to them, his eyes full of excitement of the shocking news.

He had thought the Decimo was not planning to marry…

Maybe he had a mistress?

"So, how is him, the one that teaches you?" Lee asked as he decided to lead the teenager back to the Tenth's room, sure that their boss would be looking for his lost son. The teenager was after all, the possible future boss of Vongola.

"Eh, he's scary and very harsh with his punishments…" Tsuna shivered as he thought of his sadistic tutor, Reborn.

"Ah, indeed, everyone here in Vongola feared him of his methods with dealing with people too…" Lee replied deep in thought, recalling the times when he saw the guardians exited the boss's office full of injuries.

The Vongola Decimo was indeed harsh with discipline; even his own son admitted that.

"Yet, he is strong!" Tsuna managed a grin, thanking Lee before he disappeared in a thick cloud of smoke.

As Lee frowned as the mysterious disappearance of the brunette, he failed to notice Reborn observing him, a wide sneer on his face.

The tutor knew that judging from Lee's wild imagination and so-called conclusions, troubles were to brew, really. Well, Reborn was not going to say that Lee was wrong to say that the younger Tsuna was a possible future boss to Vongola…

"As I was saying, I'm thinking whether I'm really staying single all my life." Tsuna sighed as he once again sat at his table, waiting for Reborn's response. Maybe he should take a leave and fly out of country for a vacation…

He was a grown man yet here he was, still struck at his desk, with no time to fall in love.

"If it's an heir, I suppose you don't have to worry about your subordinates fearing that you have no one suitable to choose from." Reborn grinned as he sipped his coffee and pulled at his fedora.

Not understanding what Reborn was saying, Tsuna shrugged and flipped through a file, only to be roughly interrupted by his door exploding into pieces.

"Quite the charmer, aren't you, Vongola?" Mukuro was the first to step into the office, his face smug.

"…" Hibari's face was expressionless as he took a seat on the couch in the room.

"You are extreme! I'll teach your son boxing!" Ryohei burst out, his fist punching the air.

Tsuna raised an eyebrow. His son?

"Ha, Tsuna, you should have told us that he have a cute son that looks like you!" Yamamoto good-naturedly laughed as he took a seat.

"Boss, you could have told me that you are married! I could have helped you with your wedding and help take care of your son, the next boss!" Gokudera pleaded as he too entered the room.

As his guardians started asking his questions that did not even make sense to him, Tsuna could not take it and growled.

"I'm not married, dammit!"

That got everyone's attention.

"Oh, so you are a flirt."

"So your son is from a one-night stand?"

"I didn't know you had it in you, Dame-Tsuna." Reborn added, his smirk stretching wider and wider as he stared at Tsuna's reddening face.

"What son, I don't have a son!"

"Oh, so mean, not acknowledging your own heir."

"I'll help you take care of the next boss, don't worry!"

His eyes narrowed in annoyance, Tsuna somehow felt even more puzzled by people assuming who and what he was. He was going insane every minute.

"I said, what is the meaning of this?"

As everyone froze, Reborn silently smiled to himself. Oh, Lee was so going to be in a deep trouble.

Oki: Hope ya all enjoyed it! :D
