A/N:Hello! This is a super late birthday fan fiction of our beloved Gokudera Hayato. I promised to myslef and to him (not that he cares anyway) that I'll make something for him when his birthday comes but I've been too busy with things, and I wasn't happy with the first two plots I wrote so it took me sometime. Anyway, if you're reading this, I hope you'll like it. Do let me know what you think about the story and everything else on review. Thank you :)

Disclaimer: I do not own Katekyo Hitman Reborn! But this story is.

Chapter 1: Surprises and Impulses

A teenage boy was lying on his back on a red sofa, absent-mindedly flipping through the channels of his 24-inch flat screen. He was bored: letting out annoyed mutters occasionally as he found most of the channels full of nonsense and not worth his time.

He finally gave up; he unceremoniously put the remote control on his center table and sat up. The red wall clock hanging near his bookshelf told him that it was already quarter to three in the afternoon. He scowled at it for a moment and his face suddenly broke into a smile.

"Tenth's coming over today."

He reached for his cellphone buried in his pocket and opened the message he had received from his revered boss yesterday and reread it, even though he knew he had memorized it at heart the first time.

"Gokudera-kun, can I come over tomorrow at around 4:30pm? There's something I want to discuss with you alone. If it's okay with you. ^_^"

Of course, Hayato immediately sent his reply the second he had read the message.

"OF COURSE TENTH! IT'S MY HONOR TO RECEIVE YOU IN MY HUMBLE HOME! I'LL BE WAITING ENTHUSIASTICALLY FOR YOUR ARRIVAL!"

Hayato ran his fingers through his silver strands of hair, trying to keep his bangs away from his face. The smile still plastered across his face. One ford from his beloved boss's message held his gaze, and unconsciously, it escaped his lips so soft it could easily be erased by the wind.

"Alone..."

He finally stood up and stretched his arms, and decided that he should take a shower now to remove the sticky feeling he had on his body as he had sweated a lot cleaning his whole house earlier in preparation of the coming of his great Tenth on his humble home. He knew that most of the dust particles from earlier clung to his body, and it gave him an irritating feeling.

He walked in to the bathroom and started stripping off his clothes; starting from the white long-sleeved shirt with printed skulls at the chest area, then his black skinny jeans, then his gray foreign branded underwear. He folded his used clothes hastily and placed it on top of the washing machine and proceeded to the sink.

He stared at himself in front of the mirror, ogling at his own reflection. His bright green eyes taking in every detail of his face; his slick, shiny and slightly wavy silver hair, his straight, pointed nose, his finely shaped lips, nicotine starting to blend in its natural redness, his perfectly carved jaw and high cheekbone, and his pale, smooth skin. He was aware of his good looks, but honestly, he just didn't give a shit. Being good-looking didn't help him from the rough situation he was in back when he decided to be an outcast. If anything, it caused him problems from annoying women. He would receive indecent proposals from teenage whores to old hags and they refused to leave him alone. He had come to hate almost the entire species of women, well with a few exceptions...

He tore himself away from his thoughts and shook his head. Now is not the time to think about the bad experiences, he told himself. His boss was coming over, and they would be alone; no annoying brats, no baseball idiot, no lawn-head, no scary and sadistic-slash-home tutor. Wow, at leas there's a little happiness for me today. The 'sky' decided to smile upon me today. He smirked at the person on the mirror, his chest swelling up with happiness. With one last look at his reflection he proceeded to open the shower and let the water drops fall on his skin and slowly wet him completely.

Hayato was sitting on his sofa, his legs crossed, and sitting on his lap was his copy of Complete Encyclopedia of Mythological Creatures. He adjusted his spectacles on the bridge of his nose and glanced at his wall clock; it was now 4:20 pm. He stood up and strode towards his mirror standing at the corner of the room, beside his speakers and by the window. For the umpteenth time, he checked on his appearance. He was wearing a light grey V-neck shirt and bleached jeans, white belt with a metal head of wolf on the waistband. His wrists were covered with usual metal-studded leather bands, and hanging on his neck was his army necklace with his name carved on one side, nicely placed on his chest. He straightened his shirt and adjusted his pants. He carefully tousled his already carefully tousled and waxed hair, checking if there was a strand sticking on the wrong direction. He checked his teeth and blew a breath on his hand to check if the minty smell of his toothpaste still lingered, and it did. He huffed and gave himself a satisfied smile and thumbs up. Then he sniffed his shirt again; he forgot to put on some cologne. He marched to his room for his bottle of perfume.

4:27 pm and Hayato heard his doorbell ring. He immediately strode off towards the door, grinning from ear to ear, and opened it.

There standing on the other side of his door, was his timid-looking boss and friend. His mousy, fluffy hair standing in every direction, which was oddly natural, his brown eyes looking up at him, wide and bright and his lips curved in sheepish smile. He looks so adorable like that. Hayato mentally kicked himself. His hands though, Hayato noticed, were occupied with bags, one on each side. Hayato made a movie to carry his belongings inside but Tsuna shook his head abruptly, and took a step backwards.

"No, no, no! It's fine! Let me, please!" said Tsuna sounding panicky.

"Oh!" said Hayato, raising both his hands. "I'm so sorry Tenth! That was so rude of me. Please forgive me." he said while bowing so low. He knew that his face was so red from humiliation.

"Please stand up Gokudera-kun! No need to apologize." said Tsuna anxiously. "I-it's just... you'll know later."

Hayato stood up at once, his eyebrows raised. He was now curious as to what those contain. Deciding he'd learn about it later, he signalled for the other to come in.

"Okay then Tenth. Please do come in." he grinned sheepishly.

"Thank you." said Tsuna as he stepped inside. "Pardon the intrusion." he removed his shoes and slipped on the house slipper Hayato gave him, and followed the former to the living room.

Hayato lead them into his red sofa and sat done. Tsuna carefully placed the bags at the center table. (Hayato noticed how Tsuna was gentler on the purple bag.) Tsuna briefly looked at him in the eye and then scratched his head.

"Um, can I go to the kitchen?"

Hayato was caught off guard by the question. He blinked at Tsuna before he recovered.

"What is it Tenth? I'll go get it for you." and he stood up.

"No, please." said Tsuna gently, smiling. " Please sit down. I'll explain later when I get back." he pushed him down back on the sofa and trod towards Hayato's kitchen.

Hayato remained silent, feeling a bit nervous. He heard the faucet open and the running water flow down the sink, then the soft banging of his cabinet doors, then clinking of the utensils, and the soft footfalls of Tsuna as he went back to him.

Tsuna set down the pair of plates, forks and bread knife on the table. He threw a quick glance at Hayato's direction and his ears started going red. He cautiously took out the square white box in that purple bad and laid it on the table. Hayato was watching his every move, unsure of what was happening. Then Tsuna slowly took out another box from the white bag, this time though, the box was bigger compared to the other one; it was neatly covered in red with black polka dots wrapping. He sat down closely next to him. His cheeks were tinted with red as at Hayato. Hayato on the other hand, gaped at Tsuna, then to the box, then back at Tsuna. His heart started thumping wildly, sensing what was this about. He wanted to say something but he didn't know what to say. And he was afraid he might have just been assuming...

"So, um," Tsuna started, adjusting on his seat so as to face Hayato. "Um... um... Happy sixteenth birthday!" he blurted out. His eyes shut tight and his arms stretched out as he pushed the box on Hayato.

"Tenth..." said Hayato, his voice trailing off. He warily peeled off the wrapping, and his eyes almost popped out when he saw the content; it was a set of books with three thick volumes of The Legends and the Extraterrestrial Beings by Giorgio Coppen. He saw the set of books on display by the bookstore's window the other day when they were out shopping by Reborn-san's orders. He was planning to purchase it but he remembered that he had just paid for his apartment rent and all the money left on his savings was barely enough for food.

"I saw you the other day looking at that, and you seemed like you really wanted it and well," Tsuna hesitated, scratching his head "I was also thinking o what gift should I buy-"

"T-tenth, you shouldn't have bothered, really." Hayato still couldn't believe that he had just received a gift from Tsuna. He was gawking at him not knowing what should he say.

"Gokudera-kun," Tsuna scooted closer, Hayato's face grew rigid. "Just accept it. I bought that because I wanted to." he held his gaze for a moment, trying to tell him wordlessly that he wouldn't take no for an answer. "So shall we eat? I also baked a cake though I'm not sure if the taste is okay." said Tsuna worriedly, frowning.

"You also baked a cake? " said Hayato faintly.

"E-eto, I tried to. I asked my mom's help though." Tsuna said smiling reluctantly while massaging his neck.

Hayato felt a lump stuck in his throat. He could not speak. A surge of emotions started welling up inside him and he felt like his chest might explode. This boy in front of him, how could he be so kind? He had already given him so much, like friendship, acceptance in the family, his smiles, and so any more. And despite all that, his Tenth still had bothered to buy him a gift and even bake a cake fro him, when he didn't even mention to any of his friends that his birthday was coming up. He didn't know what to do anymore, how should he repay the kindness of the timid-looking, adorable guy that was Tsuna. Before he could stop himself, his body moved on its own; he set aside the gift he was holding. Then his left hand grabbed Tsuna's right wrist on him and then hugged him. He rested his chin on his shoulder and breathed in his scent. He felt both of Tsuna's hands rest on his arms. He squeezed tighter and murmured his Tenth's name on his ear.

"Tsuna..." Who would've thought Hayato could do something like this to his own revered boss? To own his dictionary, this act was considered a disrespectful act punishable by death by the right-hand man. But he couldn't care about it now. He'd regret it later, he knew, but seconds was all he needed, and he'd let go.
