Okay, so, first of all, I decided to just make the last, useless chapter as an Omake. And honestly, I just got this idea randomly, so yeah. Hope you like and enjoy it. Love you guys!~

=================================================================

It all started with Hibari trying to take Tsuna out on a friendly date. Okay, its actually a date. And, Tsuna, being dense, and not sensing Hibari's hidden or true intention, agreed to the plan, right away. And that's when all chaos broke loose.

*****************************************************

No one's POV

Tsuna is having a quite great day. Ever since the defeat and the new alliance between Scott and Vongola Family, all is well. A little problem with his Guardians is nothing that he couldn't handle. And then, Reborn is there. His sexy, yet, sadistic lover/ boyfriend.

After the start of their relationship, Tsuna ended up on telling his family about them. He said that he can't really lie to his family, or something along those lines.

The door of Tsuna's study opened, and came Hibari strolling in.

'Wait, as far as I know I didn't do anything that would anger him! So why is he here?!' Tsuna thought nervously as he watched Hibari walk towards his mahogany table.

Hibari suddenly glared at him and that caused Tsuna's eyes to grew wide with fear.

"Omnivore." In Hibari's dictionary, such greeting actually means, 'Hello.'

"H-Hibari-san, w-what can I h-help you w-with?" He asked the man, praying to all Gods above that its not something that would result to him being dead.

"Go out with me."

That single sentence made him stop. Okay, rewind, pause, process. What? Okay, rewind pause, process. System buffering.... buffering.... still buffering.... ding!

"What?" What the heck? Tsuna's sure that he processed the information already. So why is it that he's reply is stupid like a simple 'What?'

"Omnivore, I'm asking you to go out with me for the day. Just you and me."

Is this some kind of dream? Or nightmare? Or both? Or a sudden prank? Seriously? Kyoya Hibari, the strongest and toughest Guardian of the current Vongola, the demon prefect, is actually asking him to go out with him? Dream? Maybe a bad dream?

"Hibari-san, are you sick? Do you have a fever? Or colds? Or cough? Anything?" All of his questions was answered by a single glare.

And that sent shudders to Tsuna's spine. "Okay! Okay! Please don't bite me to death!" He replied frantically, hoping that the prefect would accept his late reply.

Hibari just hummed in satisfaction and turned to walk to the door. But before exiting the particular room, Tsuna shouted, "But let me ask Reborn first!"

That shout made Hibari stop for a moment and glare at him with something behind his eyes. Anger? Hatred? No, its more like jealousy.

"Okay, later then." Was Hibari's cold reply.

And with that, Hibari left a dumb founded Tsuna.

*

Tsuna was debating whether to tell Reborn or not. Its not like he's doing anything, bad right? He's just going out with his Cloud Guardian. Nothing bad, right? It's not like he's doing something behind Reborn's back, he reassured himself.

And so, making his mind up to not say any of this to Reborn and remembering that on the very same day of his friendly date with Hibari is also the same day that Reborn will do his special mission with Colonello and Mammon.

Walking in the hallway to his private quarters, Tsuna saw Reborn walking in the different direction and run to him.

"Reborn! I thought that you're going to a special mission with the other Arcobalenos?" He asked the taller male.

"Supposed to. But fortunately, Colonello is sick and Mammon doesn't want to continue the mission for this day, stating that Colonello is specially needed for this mission. But, thanks to that, I have a day off for today." Reborn said as he bent down to give Tsuna a kiss on the lips. Tsuna returned the kiss eagerly, opening his mouth, inviting Reborn's tongue to his.

When they parted, Reborn saw Tsuna blushing and he smirked. "Say, do you want to do 'it' today?" Reborn teased.

That statement made Tsuna blush harder. "I-I can't. I have an appointment to attend to."

When Tsuna stuttered, Reborn looked at hum suspiciously. But he decided to not push the topic further. "Okay. I'm just going to spend time with Fon then. He said that he needs help with something."

Tsuna smiled at him. "Sure, say hi to him for me."

"Got it."

*

Tsuna waited at the park that Hibari texted him the address of. They agreed to meet at the said place secretly. He's actually hesitant to go here, but he thought that if he doesn't show up, HIbari might be angry at him, big time. And, angering the said Guardian is more than a taboo. 

Minutes later, he saw a familiar figure walking to his direction. Tsuna gulped, praying that he made the right decision.

The figure stopped walking in front of him and took one of his hands. "Come, we have a long day ahead of us."

*

Unknown to the duo, a pair of sharp eyes is following their every move. And, that the owner is doing his best to not burst a dark aura, instead focused on hiding his presence.

'So this is the appointment, huh?'

To say that Reborn is jealous would be an understatement. He's over freakingly jealous right now that an assassination assignment would be awesome for the time being. He's watching Tsuna and Hibari right now, and that every now and then, his eyes would twitch whenever Hibari touches Tsuna. His Tsuna.

He sighed and tried to calm himself. Key word: tried. It was unsuccessful due to Hibari putting an arm around Tsuna and Tsuna smiling nervously at him. Thanks to his unending self control, he managed to look away.

'Damn, what should I do?'

Normally, being the strongest hitman there is, Reborn can do almost anything. He's a tactician, and certainly a genius and prodigy. He's the best of the best, dang it! That's why he's really lost right now. He can't just burst into the scene and beat Hibari! Tsuna would be angry at him. He can't just watch them, too! He can't do that. He will probably kill Hibari if he does. Besides, he's possessiveness will most likely destroy all of his calm solutions.

'Seriously, what is the most logical way to solve this outrageously difficult and illogical problem of mine?!'

Yup, a real genius, Reborn.

Gokudera's POV

Right now me and Yamamoto is in on a park. I don't exactly know the name, but, Yamamoto picked this place up randomly. He said that he knew Reborn-san, Hibari and Tenth is not in the mansion, and stated that it will be the perfect timing to escape from our duties and go to a date. I hesitated at first, but he said that we can help Tenth at his work after this, so I reluctantly agreed.

And, honestly, I'm bored. Yamammoto kept on babbling about things that I don't know about. That is, until I saw Reborn-san seating on a bench, leaning his back against the post of the shed. He looks like he's investigating or something. No, actually all he's doing right now is glaring at someone.

I nudged Yamamoto with my shoulders. "Hey, Yamamoto, you said that Reborn-san is out for a special and top secret mission with the other Arcobalenos, right?"

He nodded, "Yeah, Tsuna told me that a day ago. Why?"

I looked at him sharply and pointed a finger at where Reborn-san is. "There! Reborn-san is here!"

He looked at where I pointed an laughed as he scratched the back of his neck. "Hahaha, but Tsuna said that Reborn-san, Colonello and Mammon is going to Ireland for the mission. There's no way that Reborn-san can be here!"

I just glared at him. "Then explain how is that a guy that loos like exactly Reborn-san is here."

He just sighed and pulled my hand, making me blush a little. He smirked "In any case, let's go somewhere else. 'Cause right now, I'm positive that's Reborn-san. Just look at that dark aura and blood lust."

As I looked back, sure enough, Reborn-san is releasing a very dark aura and is growling like a wolf. His eyes is a little red, and I can sense his blood lust even from here. I shuddered in slight fear.

"Yeah, we better get out of here before all hell breaks lose."

*

Reborn doesn't care if Tsuna will be angry at him if he kills Hibari on accident. And he certainly doesn't care if people stares at him and gets the shudder. He can't suppress his aura anymore, and his blood lust is in its peak. No holding back now.

'But, hey! It's not logical to just burst in the scene and create a chaos! That's illogical way of your thinking!' His mind tried to argue.

'Damn logic then.' Was his only reply, as he pushed his previous thought away.

He walked to where Tsuna and Hibari is, and as swift as wind, he carried Tsuna on his arms, bolting out of the scene quickly, fast enough that Hibari can't catch up. Before Tsuna can squeak, he covered his mouth with his own. The gasp that Tsuna made became Reborn's chance to slide his tongue to Tsuna's mouth.

Tsuna moaned quietly into the kiss and Reborn smirked. Parting from the kiss, he stopped at a special nearby place that Reborn used before as a hidden base. He used it before when Colonello refused to let him hide at his place, and he decided to just make one. He also goes here when he's got nothing to do at times, noting that this one is just near from the mansion. He improved things, security and such at this place, whenever he's on a break.

Opening the hidden lock on the door, the one that was hidden on a common rock, and typing the password and the eye scanner, Reborn made sure that the mist flame is still functioning just fine, before pressing a button and before Tsuna knew it, they were already in an unfamiliar place, with a couch, flat screen TV, and devices that seems to be built for tracking people and some guns that are hanging on the walls with a few bombs and grenades at a mini table.

Tsuna looked at Reborn, "Hey Reborn, where are we?"

"My secret haven."

"And why are we here?"

"Because its near."

"How come I don't know about this place?"

"Never asked me before."

"Should I really ask you first about things like this?"

Reborn looked at him, a little irritated. "Dame-Tsuna, stop asking questions."

"Why?" Tsuna looked at him, and his face held innocence.

"I know that you want to annoy me further, but no." Tsuna grunted at his response.

Reborn sat on the couch and looked at the standing form of Tsuna. "What?" Tsuna asked.

"You're going to stand there for the rest of your life?"

Tsuna grumbled but took a seat on the opposite sofa.

They stared at each other, not making any noises or effort to break the silence.

Tsuna sighed and leaned his back at the pillow behind him. "What's your deal anyway? Your as grumpy as ever."

Reborn just stared at him. "You. You're my deal. You're my problem here." Reborn answered, straight to the point.

Tsuna blushed. "What about me? What's the problem with me?"

"You went out with Hibari, not asking for my opinion. You let Hibari take you to places. Lastly, you let him touch you."

"Are you jealous?" Tsuna taunted.

"And what if I am?" Tsuna blushed at that.

Reborn got up from his seat and faced Tsuna. "Look, Tsuna. It's not like I'm saying that you can't let the others touch you or go out with you. My point is that, you're dense as f*ck, cute as hell, and lovely. That's where my point lies. I mean, a guy is trying to hit on you, and you still doesn't notice. Usually, it's okay, 'cause I'm with you most of the time. But I'm not at your side, everyday and every time Tsuna. So please, tell me if you have to go to this things. And, please, please, never, ever, let your guard down when you're around with Hibari. Just. Not. Him. Understand, Tsuna?"

After Reborn's mini speech, Tsuna found himself blusing as red as tomato, and felt himself fall in love with Reborn even more. To Reborn's surprise, Tsuna hugged him and nuzzled his face to his neck.

"Oh, Reborn. That's why I love you. You're possessive side is my favorite among all your adorable traits."

Reborn's eyebrows twitched. 'I wasted my saliva and that's his answer?'

"Of course I understand you. Promise, this won't happen again. Love you, Reborn."

"Tch, whatever you say, Dame-Tsuna."

And with that, Tsuna's supposed-to-be-horrifying-day became one of the most valued one on his life.
