04 – Unexpected

-Omnivore.-

-Yes, Kyouya?-

-Fight me.-

Tsuna blinked, looking up from his paperwork. -What? Why?-

As an answer, the Cloud Guardian took out his tonfa and assumed an attack stance. The brunette stood abruptly and lifted his hands.

-Wait. Ok, I'll fight you… Just, not here… Wait for me in the training room, okay?-

Hibari huffed and retracted his weapons. After he left, Tsuna slumped on his chair, sighing. Why the hell would the boy want a fight, now? Jeez… So random…

-I think he's worried.- Reborn's voice was oddly near to his ears, as it has been for the last month.

Tsuna lifted his head to look at his side. The hitman was leaning on the desk, hands in the pants' pockets, fedora tilted to shadow his eyes. His figure was tenser, however. Maybe because Fon kept interrupting his doings every single night.

-Worried? About what?-

Reborn touched his neck with a finger, exactly where he had left a mark the night before. Tsuna blushed and covered the spot.

-Even if you cover it, to the trained eye it's obvious. He is worried.-

The Boss sighed and shook his head. -Kyouya… Worried… That's so strange.-

-Maybe.-

-But, why a fight?-

-Judging his personality, he wants to be sure that you're strong enough to protect yourself.-

-… They're such mother-hens…-

-I can sympathize.- Reborn glanced at him in disagreement.

-I have no choice. This dinner can't be avoided. And none of you can accompany me.-

The hitman snorted, grabbed the armrest with his hands and spun Tsuna to face him. He leaned forward.

-I don't care. I'm coming. With or without your consent.-

-You're so stubborn…- The brunette whispered. -All of you.- Reborn smirked. -I can't keep you away, not even for the time of a simple job dinner.-

-Obviously.-

The kiss was sensual and slow, with half-lidded eyes. A tongue trying to escape the other, but captured soon. Tsuna engaged battle softly with a hum, surrendering immediately to the dominating man.

A cough made the two separate and look at the open door. Fon was standing there, arms crossed on his chest and gazing at the floor. The brunette freed and stood, rapidly leaving the room.

-Kyouya might destroy the training room again if I keep him waiting.-

With that, the two Arcobaleno were left in the office, carefully looking at each other. Reborn took his mug of coffee from the desk and went to sit on the sofa. Fon unfroze and sat in front of him.

-He's the reason, then.-

The hitman arched a brow and sipped his drink.

-As to why you decided to join a Famiglia, in the end.-

Reborn hummed.

-All these nights… I've been interrupting you…-

This time he growled.

-I'm sorry…? My friend, this is so unlike you.-

The man put the empty mug on the table. -You think so…-

-Reborn, you're serious about someone. This is unlike you.-

-And what's the matter with that?-

-Why?-

The hitman huffed and crossed his arms. -I just want to. Nothing more, nothing less.-

Fon smiled. -That speaks volumes… You're attracted by the Decimo Boss of Vongola.-

-Will you stop getting in my way?-

-I don't know… I guess the real reason why the Guardians arranged the hiring of bodyguards is you.- Reborn's smirk was enough of an answer. -So, my job is to protect my Boss from you.-

-Very well.-

The hitman stood and left. Fon sighed, looking at the empty doorway.

-You already have some plans, as always.-

Tsuna got off the car and checked his black cape and suit. He adjusted the mask one more time, before walking in the luxurious restaurant. Red velvet walls, wooden golden tables expensively laid, white chairs circling them neatly, rich chandeliers dangling from the dark ceiling with lit candles and drops of crystals. Everything reeked of aristocracy.

Vongola Decimo resisted the urge to scrunch up his nose and followed the owner through the still empty wide room. The man, old and wrinkled, but with kind facial features, called an elevator and urged him inside, pushing then the tenth key.

Tsuna was not feeling well about this. His intuition was howling like a caged wild beast. Reborn was nowhere to be found and, although it could have been a nice thing, the brunette couldn't brush off the sensation of uneasiness. Something… uncomfortable… was going to happen.

He got off the elevator and strode through the alleyway, leaving the man behind. He knew the place, after all. Tsuna opened the door at the end and entered the wide room. It was the same as the restaurant on the ground floor, but the table was round and big. Tall, wooden chairs with red paddings surrounded it, twenty in total. Some were already occupied.

The Bosses stood and nodded in greeting as the brunette took his own seat. Dino Cavallone, Enma Kozato, Xanxus, Iemitsu Sawada, Yuni, Byakuran. Tsuna smiled and looked around.

-Good evening. I'm sorry for my lateness and thank you for attending. Where are the others?-

-They're not coming, Vongola Decimo.- The white-haired man said with a chuckle.

The brunette sighed inwardly. -I see. Then let's begin.-

-Are you sure?-

-Positive.-

-Then we must be quick.-

Hayato jumped down the rooftop and landed on the balcony of the restaurant. Reborn followed suit with a smirk and Fon with a sigh.

-Where are the other Guardians?-

-They're organizing the squads down below.-

The martial artist sighed. -Shouldn't this meeting be guarded?-

-It is.- The Storm Guardian picked the lock of the French window. -But they're not us. Also, considering no one has ever attempted to do something in this occasion, they do not expect anything.-

-Beginners…-

-More like not interested.- Reborn said, entering with the other two. -They're paid for this, but not affiliated. They do not care.-

-But we do.- Hayato walked down the corridor and stopped at a corner, checking the two sides.

They passed by several doors for ten minutes, coated in Mist flames. As time ticked by, the Storm's anxiety flew through the ceiling and past his own record. He didn't know how the hitman managed to learn about the incoming attack, but the whole thing… Was unnerving.

Some months before, his Boss had disappeared into thin air after a meeting gone wrong. Only to find him almost naked, flushed and slightly shocked in a villa hidden by an illusion. He was unscathed, but… Decimo wouldn't tell them the name of the shit. Then, the same son of a bitch had entered their base as if it was a playground in a park and ravished his Boss. In the worst possible meaning of the word. And still, Juudaime wouldn't tell anyone who the culprit was. So, all the Guardians had taken matters in their own hands and arranged an urgent interviews' session the same day. Hiding those from their Boss had not been simple, but they had managed to lock him in the office.

Who could have imagined that four Arcobaleno would have showed up? It was amazing! Of course, it was because Tsuna was amazing and incredible and kind and powerful. In the end, those four were hired… Two not for the main reason, but… who cared. The Vongola's manpower was higher than ever. Plus, Reborn had proved to be useful, wise and strong. A nice addition, indeed. Now, if they could only deter whoever was barging in the Boss' quarters… Fon had said he was taking care of the matter, still…

But, back to the problem at hand. Hayato stopped at the next corner and hid behind it, looking in the alley at the right. Clear. The door of the meeting was at its end. He sighed silently.

-That's the room. What exactly are we waiting for?-

Reborn glanced at the boy, then at his fellow Arcobaleno. -Police.-

Tsuna sighed. -Are you sure about this, Yuni?-

-Yes, Decimo. But we don't know when.-

-Then we should be prepared.- Dino said, drinking some wine. -For all we know, they could be attacking us right now.-

-Tch. I highly doubt it.- Iemitsu countered.

-Trash.- Xanxus added, grabbing a bottle.

The brunette ate a fork of the pasta and hummed. Indeed, it was an uncomfortable situation, considering three over-protective mother-hens were waiting for him just outside of the door. Those scoundrels… He could very well defend himself from whatever. And…

-You seem troubled, Decimo.- Byakuran chuckled.

Tsuna gulped and looked at him. -My Guardians are playing at who makes me snap first, not doing what I say.- He replied with a scoff. -And a police officer is hiding behind the curtain.-

It all happened in less than a second. A man in a grey suit jumped from his hiding spot towards Tsuna. The latter took his glass and drank the wine, eyes closed. Reborn destroyed the door and gripped the man's throat, making him hang in the air, knife scattered on the floor.

-First, I must apologize.- The brunette left the glass and stood, going to the hitman's side. -My bodyguard takes his job quite seriously and doesn't stay put when I say him to.- The other Bosses were half-standing, eyes slightly wide. -Well, it's convenient most of the times.- Tsuna lifted a hand to the man's chin. -You're either brave or the last wheel. Who sent you?-

He nodded and Reborn launched the man, lean and muscular, blonde, against the wall. Decimo inched a step forward. The policeman coughed, hungry for air, and glared at him. The hitman was about to hit him, but Tsuna put a hand on his chest to stop the assassin.

-Well? You're going to die, anyway.-

-Then kill me.-

The masked man hummed and smirked. -There are many ways to kill someone, you know? Torture is my favorite. You must be well informed on my methods.- He bend his knees, looking straight in his eyes. -I'll let my Mist Guardian blow off some steam. Hayato, Fon, I know you're there. Take him to the mansion.-

As Tsuna stood again and went back to the table, the two did as told and disappeared with the screaming man. Reborn, instead, approached him and stayed at his side, arms crossed.

Yuni smiled. -Decimo… Who is he?-

Oh, right, blessed be not knowing… -He can say for himself.-

The hitman smirked. -I'm Reborn.-

Again, he bathed in the muffled gasps and Dino's shriek. Tsuna sighed. He knew what was going to happen…

-So, he is the one…- Iemitsu's rage could be felt at a mile distance.

-The one..?- He feigned ignorance. -I hired him as my bodyguard, what's the matter?-

The man stood completely and sped forward. Tsuna sighed once more before blocking him with a kick to his face. His father hit the wall with violence and it was destroyed. More paperwork…

-I don't think this is the place and time for you to act rashly. Reborn, what's happening?-

-Police is surrounding the building.-

Tsuna scoffed. -I'll let all of you thank my men in a later moment. You'd want to disappear, now.-

Everyone stood and walked away through the broken door. Iemitsu regained his feet and glared at them.

-Ts-…-

-Not here.- Tsuna seethed. -We have to go.-

-Are you crazy?! You hired the fucking World's Greatest Hitman to be your bodyguard?!-

Tsuna was sitting in his office, head on hands, covered, eyes closed shut. His father was walking the room up and down, screaming his disagreement and worries. Fon and Reborn were on the door's sides, quiet and amused. His wounded Guardians were getting treatment by Ryohei while Mukuro was busy taking care of their captive.

-Is he the boyfriend you keep hidden from me?!-

Tsuna looked up and glared with fury, fighting down a blush. Reborn smirked and Fon coughed. Fortunately, Iemitsu was too focused on his son's dangerous eyes to notice those reactions.

-Even if, father, what's your business with the notion?- His tone was cold, slicing.

The man hid a shiver. -You're my son, how could I see you with such a man and not do anything?-

-Then you do not trust me.-

-It's not like that…-

-No, it's exactly like that. Moreover, father, this is my business and you should mind your own.-

-Tsuna, you can't trust him…-

-I've been silent, Iemitsu, but that doesn't mean I'm not here.- Reborn said with his velvet and amused voice.

-I do not care. You're dangerous for my son.-

-Well, I can't deny that.- His smirk widened. -But it's my business what I want to do to my lover.-

Tsuna blushed furiously, Iemitsu spluttered, Fon coughed and Reborn chuckled. The brunette brushed a hand on his face and went between his father and the hitman. The CEDEF's Boss stopped and almost crushed into his son.

-Dad, what I want to do, I do, stop being a mother-hen. I have already enough of those.- Tsuna smiled. -Trust me. Mom would have agreed, too.-

He felt a shit nominating his dead mom, but it always worked. Besides, it was not a lie. Nana would have surely let him free to choose.

Iemitsu's expression softened, looking at his son and at the floor. -I think you're right…- Tsuna suppressed a relieved breath. -But…- Then deflated. -I'll keep a close eye on him.- He glared at Reborn. -Don't you dare joke on this.-

The man left with a sigh and a nod to his son, Fon following him outside.

-Reborn…- Tsuna whined, closing the door. -You planned this.- He turned and looked at the hitman. -So unpredictable…-

The man's smirk was still in place. -Of course. But I didn't hear a refusal this time.-

-Refusal?- Tsuna sat on the sofa and took off the cape and the jacket. -To what?-

Reborn did the same and grabbed his arm. He pulled the boy on his lap, making the other face him. Their chest touched as Tsuna circled his neck with his own arms. The hitman kissed him shortly.

-You're my lover.-

The boy blushed and hid his face on the other's shoulder. -I didn't, you're right.-

Reborn bit his earlobe and whispered: -Then, it's a consent?-

Tsuna shivered and nodded. -It is… Though, I still don't understand why on earth you chose me…-

The man licked his neck, under the earlobe, sucking the skin and leaving a red mark. -In the beginning…- He brushed hands against the other's sides. -It was simple attraction. I saved you only because of that.- He made another mark, circled with teeth, under his chin, earning a muffled moan. -Then, it became curiosity. How could you, scrawny and short, be the Vongola Decimo…- His hands slid down to the hem of the black pants. -When you woke up, I understood. Your collected, strong personality.- He hooked the thumbs on the belt and massaged his ass slowly. -Your acting skills are impressive, as is your ability to lead.- He squeezed and smirked. -It changed into lust. One I did not expect.- Tsuna tried to push him away but Reborn circled his sides and held him. -One I do not regret.- He let the boy lift his blushed face and looked into his eyes. -One I want to cultivate.-

Tsuna held the gaze and let his forehead lean on the other's. -That's the closer to a confession I'm going to ever hear, right?-

Reborn chuckled and captured his lips again. The fedora fell behind the couch and Tsuna started massaging his scalp, mewling in the heated kiss. He felt the tongue interlace his own in a slow and exciting movement. The brunette combed some fingers through the silky spiky black hair and tugged a bit, making the other growl. That sent new pleasure shivers down his spine and Tsuna pressed his body against the other.

The kiss became harsher and toothy, with muffled moans. Reborn positioned a hand on his side, soothingly going up and down, and the other on his ass, squeezing lightly. They separated to breath for a short moment, before clashing back and with more need. The hitman started undoing the buttons of the shirt while biting on the boy's lower lip. A hand slipped on his shoulder, letting the shirt slid down a bit, while the other moved to the belt. Reborn touched the skin and, like a feather, he traced the collarbone, the sternum, the abdominal muscles.

It was then that someone knocked at the door and it opened. The two separated again, Tsuna slightly distracted. It was quite a sight. The Vongola Decimo straddling his bodyguard, half-naked and flustered. Hayato fainted with a thud. Reborn chuckled and Tsuna sighed. Then Mukuro came into view. And the brunette found himself sitting on the couch, looking up as the hitman ran and left through the window, probably to take the fight outside, followed by his Mist Guardian.

Tsuna rearranged his clothes and stood. He took his right-hand, arm on his shoulders, and took him to the silver-haired's room. His life was going to be even crazier. By tomorrow's morning, every one of his Guardians were sure to know the latest events and he would be forced to explain…

Wait… Did he… Plan this, too…? The damn man… He could agree with one thing, though. This was all totally unexpected… And he wanted it. Now more than ever.

Thanks again for reading till the end. This is a story with poor content, written in 5 days and coming out of a ridiculous black hole. Seriously, I did not plan anything xD See ya!
