A/N:I'm very very very sorry! This story was named Careless, but I suddenly had a new twist on the plot and it wouldn't leave my mind no matter how much I tried! I tried to type the next chapter, I really tried, but I kept reminded of the new plot and... I change the story. This chapter is more or less the same as before, but I changed Tsuna and Natsu's personality to be more... EXTREME! Please review and tell me you forgive me! Please!

Chapter 1

"...morning."

"Good morning, Tsu-chan!"

"Morning Tsuna." Natsu replied to his brother's greeting. As usual, his brother's chocolate brown eyes were half lidded, as if he was so tired he can't even open his eyes properly. The slouch and the big yawn he made didn't help to change his lazy impressions. Only his spiky hair stood straight to show his vibrant uniqueness. All in all, he looked like he would topple over at anytime. Natsu secretly hoped Tsuna would be more attentive to his surroundings if the day had gone later, but he knew it was futile.

"Why didn't you wake me up?" He heard his brother asked as he grabbed a toast. Natsu finished his before answering, "I tried, but you wouldn't budge over at all."

"Mou, Tsu-chan! If you didn't stay up late last night, you wouldn't have a problem in waking up!" Nana pouted from her spot the kitchen.

Natsu wished it was the case. It would be so easy to make his brother wake up then. But Tsuna can sleep for forty eight hours without waking up and Natsu still would have the same trouble in waking his twin up.

.

"I'm not late!" Natsu shouted out when he and Tsuna arrived inside the school. Fortunately, they were all inside before a certain prefect appeared.

Natsu breathed heavily. They had run all the way from their home to the school, any human would be drained. Although not all of them would look like the both of them.

Natsu, with his natural blonde and orange eyes looked like an angel. His uniform, wet from his sweat, was plastered to his body, showing his slender build with a bit of muscle. His spiky hair wasn't bothered by all the work at all. The uniform he wore can't be said the same though. The upper button was undone. He was running his hand through his hair; at that moment, he looked like an angel, a very wet angel.

On the other hand, the other twin with his equal spiky brown hair was still slouching as usual, his hands in his pocket. His eyes were closed, covering his mesmerizing chocolate brown eyes. His slim figure, while more or less looked the same as his brother, looked more fragile (while Natsu's body was a bit tan), showing the lack of time he had spent outdoor. The weird thing was his uniform wasn't covered with sweat like his brother, although there were some spot of sweat.

"Well, let's get inside before the bell ring…" Tsuna said, not responding to Natsu's exclamation. Natsu didn't react to this, knowing his brother just didn't want to face their chairman reprimand if they turned out to be really late. Out there, there weren't any other student beside the two of them .

"Okay…"

"Good morning, Hibari-san!" Tsuna greeted the chairman cheerfully; ignoring the glare the prefect sent his way.

"Hn." The prefect replied; even though it wasn't a reply at all…

Natsu just smiled at Hibari. He walked towards the school with his brother then, their pace a bit faster than before. If Hibari was already there, the bell will ring soon. They wouldn't want to be anywhere outside the classroom when that happened.

"Why did you greet him? He won't say anything to you except for his threat." He asked his brother, curious of the answer. Every day, even when he didn't meet Hibari at the morning, Tsuna always searched for him to greet the raven.

"Well, maybe if I became a little closer to him than any other student, he will let me break a few small rules…" Tsuna replied cheekily, although he didn't look any different from usual. You must watch his tone closely to realize it.

"Hmph," the younger twin scoffed. "I don't greet him like that, but I am more close to him than you, Tsuna." Truth be told, Natsu had got into trouble with Hibari too many times he didn't even bother to remember what he did. But, opposite to the scorn he expected from the chairman, he got to be a close acquaintance with him, something Tsuna looked like he wanted.

"I know…"

They didn't talk anymore, entering their classroom as the bell rang. Instantly, they were ambushed by their classmate. Well, more like Natsu was ambushed by their classmate. Tsuna slipped by them and approached his two friends, the corner of his mouth turning up a little, indicating he was smiling.

"Good morning, Gokudera-kun and Yamamoto-kun."

"Good morning, Tenth!" Gokudera replied enthusiastically. Gokudera was Tsuna's first friend. They met in elementary school, where Gokudera was bullied by a few boys because of his foreigner looks and... well, his heritage. Tsuna didn't feel natural thinking about Gokudera's family flaw. The boys were calling Gokudera bad names, throwing him rocks.

Gokudera didn't react at all at that time. Before he would oppose them, but, after so many times hearing the same insult, Gokudera started to think the same way. If Tsuna didn't show up that time to defend him, Gokudera didn't know what he will be right now.

That time, the bullies tried to strike the rocks at Tsuna, trying to make him back off. Gokudera stood still at the side, still believing he was worthless, nobody would stay by his side after they hear the insult the bullies threw his way. But Tsuna defied his expectation. He continued to believe in Gokudera, believing he wasn't the same as his parents. The boys tried to fight him ten times, but Tsuna stayed still, his eyes was burning Gokudera's mind, encouraging him to stand up by himself, to defend himself. By the tenth times, when the weird boy with spiky brown hair still looked at him with the same determination, Gokudera began to believe that he had some worth, still held some meaning. He swore then to himself. If he didn't want to live for himself, then at least he would for this boy.

For Tsuna it was unbelievable. There was a boy who looked so strong, kneeling at the road with tears in his eyes. He was curling into himself, trying to hide from the pain. He couldn't sit still and let the bullies and the boy like that, so he acted. He can't save the boy from himself, so he tried to encourage the silver haired boy's will. He was so satisfied when the boy started to fight back the bullies, even though he didn't expect the dynamites the boy got out from… his body! Well, he didn't regret his act even once though. Gokudera proved to be a very loyal and dedicated… friend.

"Morning, Tsuna." Tsuna's eyes moved to the smiling boy at his side, Takeshi Yamamoto. The baseball player beamed when he got Tsuna's attention. He was Tsuna's second friend. He-

"You baseball freak! Greet Tenth with the respect he deserved properly!" Gokudera said heatedly to Yamamoto, breaking Tsuna's trail of thought.

"Maa, maa, Gokudera-kun. Don't be so uptight. Have you finished the math homework?" Yamamoto changed the topic briefly. It was a good choice, considering they would bicker about it all day if allowed.

"Of course! As Tenth's right hand man I must be the best at everything! Not better that Tenth though…"

"I think I didn't do it." Tsuna said after he searched his mind.

"Well, I think I have never seen you do your homework" A certain voice joined their conversation smoothly. The three of them looked toward the source. Natsu sat in front of Tsuna's desk, his expression annoyed.

"Ah, Natsu-san, you escaped your fans?" Yamamoto gestured to the students around them, all of them sitting on their respected chair.

Natsu raised his eyebrow. "In case all of you hadn't noticed, the teacher has entered the class."

"Sawada! Yamamoto! Gokudera! What are you doing? Open the book at page 42!"

All of them scrambled to get their book save for Tsuna. The teacher didn't notice it and started to explain the lesson for that morning.

While all of them concentrated on their teacher's speech, a particular brunet closed his eyes and put his head over his arms on the desk, starting to fall asleep as the teacher drone on.

This was a normal day.
