Tsuna reluctantly dragged himself out of bed at 8:30 in the morning, after Reborn's usual painful wake up call, and half heartily groomed himself. The teen ended up accidently putting on his vest then blouse, only realizing his error after rushing past the bathroom mirror. Usually in this kind of situation, the brunette's mom would be there to catch the mistake, but Nana was on vacation this weekend with the kids and Bianchi. Somewhere having to do with trees or maybe camping, that's what she mentioned. Anyway it left Tsuna to fend for himself for a month or so, having only the money Nana left him and a sadistic home tutor who would not hesitate to suck every minute of training out of the sky until the rest of the household returned. Just the thought of all the rigorous training brought on a throbbing headache, or maybe that was the Leon hammer wakeup call Tsuna received. Another usual side effect of their training sessions, that Tsuna was currently suffering, were the muscle aches. Every inch of his body was sore from all of Reborn's stringent exercises such as climbing that mountain twice, staying in HWD mode for longer and longer each day etc.

So said sadistic tutor was sitting at the kitchen table when Tsuna came down. The sun arcobaleno 'innocently' read the morning paper, his daily espresso next to him.

"Ciaossu; finally you're up. You had better hurry. School starts in 10 minutes," Reborn advised, not even giving a glance in the brunette's direction, "Also remember: training straight after school."

"Hai..."

Tsuna couldn't gather the energy to complain back - he just felt so out of it. If possible his headache had intensified in the time it took to walk (trip) down the stairs and into the kitchen. The ache had gone from a dull throb to feeling as if someone was drilling inside of the poor brunette's skull. The same pain resonated in his muscles as well. Now the young Vongola started to doubt Reborn's hammer was the source, the teen never experienced such an intense headache from the tutor's wake up calls before. Then again, it could have come about from a combination of Reborn's Spartan training and the sleepless nights that accompanied it. Both having took their toll on the weary decimo.

"Oi, Dame-Tsuna! Are you even listening to me? What in the world is more important than the topic of your training?" Reborn asked in annoyance, finally shooting Tsuna that sharp glare the brunette was expecting. It only furthered Tsuna's painful headache.

"Yeah... training after school. I get it. Have you seen the (1) non-drowsy aspirin?" Tsuna asked in reply, shifting through their worn down, frequently used medicine cabinet with difficultly. All the labels blurred together in Tsuna's distracted vision.

"Aspirin? Now why in the world would you possibly need that?" Reborn questioned, an innocent look on his face.

"Waking someone up with a five-ton hammer causes headaches, you know. Not to mention the seemingly endless muscle aches due to your Spartan like training." Tsuna scowled a bit, trying to decipher the text on the pill container he believed to be the aspirin.

"Che, I didn't whack you that hard. In fact, I went soft on you this morning because I saw how pathetic you were curled up in your bed. As for your pains… Well no pain, no gain." Reborn smirked with a glint in his shadowed eyes.

"Aha!" Tsuna found the right pill container. The brunette unscrewed the cap and dumped two pills onto his unsteady hand. Then he stashed the pill container into the pocket of his overly baggy winter jacket.

"Ten minutes 'till school starts. If you're late I'll sick Hibari on you and double your training exercises for the day."

"Hiiiieeee! I'm going, I'm going!" Tsuna acknowledged, and sprinted out of the house in haste. Dressed in warm winter attire, school bag in arm and all. The brunette ran as fast as his aching body would allow. In the brunette's sate, he definitely couldn't handle Hibari and a double set of exercises.

Upon arriving at the cross walk leading to the school, Tsuna found Gokudera and Yamamoto waiting there, leisurely as ever.

"GOOD MORNING, JUUDAIME!" Tsuna winced at Gokudera's loud greeting; it made his head throb. Much as he appreciated Gokudera's enthusiasm, he wished the silverette would be more calm and collected.

"Yo Tsuna! Wake up late again today?" Yamamoto greeted with a light hearted attitude. At least the rain guardian wasn't as loud.

"Good morning Gokudera-kun, Yamamoto. Blame Reborn and his Leon hammer." Tsuna sighed; they started to make their way towards Nami-chu.

"Maa maa, I'm sure it only felt like a hammer since you were half asleep. The kid probably woke you up with a pillow or something!" Yamamoto grinned carelessly, arms thrown behind his head in a relaxed position. Tsuna blanched, thinking if only the rain guardian knew.

"Ney Judaism~ What'cha got in your hand?" Gokudera noticed Tsuna's clenched fist.

"Ah! I thought I took these already." Tsuna surmised, noticing the white non drowsy aspirin pills held in his hand. Swiftly, he placed them towards the back of his throat on the tongue and dry swallowed them both together. Soon after he regretted that feat, the pills scratched their way down his sore throat, irritating it even more.

"Eh! What's the aspirin for? Are you in pain! Are you dying? Don't worry, Juudaime! I'll save you from dying!" Gokudera yelled with concern, The Italian pulled out his dynamite dramatically.

"I'm not dying, and bombs aren't gonna help!" Tsuna whined weakly, trying to get Gokudera not to blow something (more like someone) up.

With the commotion and Gokudera's rambling about he'd save Juudaime, a sharp pain seized Tsuna's pounding head causing him to clench his eyelid shut. He let out a small gasp. The poor teen clutched his head in agony trying to block the throbbing out and wait for the aspirin to kick in. The tension seeped through his weary bones, his aches intensified.

"Juudaime?"

"Tsuna?"

Two comforting hands placed the selves on Tsuna's shoulders, keeping him upright and steady till the brunette could open his chocolate colored eyes without pain assaulting him. A pair of sea green eyes and hazel brown eyes returned the brunettes hazy view with great concern.

"Hey Tsuna, are you ok?" Yamamoto chided with concern, shifting his eyes about Tsuna searching for what had cause his friend's sudden pain.

"Yeah, it's just a headache hence the non-drowsy aspirin. It's nothing." Tsuna smiled weakly, lessening the grip on his head.

"Are you sure about that, Juudaime?" Gokudera questioned, inspecting his friend with worried eyes.

"Hai! It's just from Reborn's brutal training. I'll be fine!" Tsuna explained hoping that they would buy it. The teen didn't want to worry his friends. Besides he didn't want to be thought annoying by whining or complaining.

"Well if Juudaime says so..." Gokudera hesitantly complied, sharing an uncertain glance with Yamamoto.

"Yep! It's fine!" Tsuna nodded, his head still throbbed but the brunette decided to switch subjects, "Aren't we late for school?"

"Nope~" Yamamoto grinned, reverted back to his cheery usual self - supposedly. Although Tsuna could sense the rain guardian was still worried. "Hmm there was something happening so they had to postpone school for two periods."

"You stupid baseball freak; I just told you! It was for a teacher's assembly." Gokudera roughly corrected him.

"A-ah is that so? Then why were you guys waiting out here if school was postponed? It's freezing out here!" Tsuna questioned with surprise.

"I forgot!" Yamamoto laughed carelessly. Tsuna sweat dropped; at least he wasn't the only one.

"I figured you two would forget, I had nothing else to do..." Gokudera explained, rolling his eyes mainly at Yamamoto.

"So at least we can take our time walking there!" Tsuna yawned; a sudden drowsiness came over the brunette.

"Ha ha~ Tired, Tsuna?" Yamamoto asked light-heartedly.

"Nah, gah just this winter atmosphere makes me sleepy," Tuna stifled another yawn.

"Then I shall blow up this winter atmosphere for making Juudaime tired!' Gokudera exclaimed, pulling out his dynamite.

"How is that even possible!" Tsuna questioned incredulously.

"Maa maa~ Now we're going to be late!" Yamamoto happily chirped in.

"Hiiiiieeeeee! Hurry up! Hurry up! I don't want Reborn to double my training time!" Tsuna whined, he sprinted towards Nami-chuu at high-speed. The silverette and blackette quickly followed the panicked teen, and promptly passed him. They were only a short distance in front though.

A red headed kid suddenly made his way into the corner of Tsuna's line of vision.

"Enma-kun!" Tsuna exclaimed with surprise "So you're late too?"

"Good morning, Tsuna-kun... yeah, I woke up late and forgot..." Enma Kozato panted, running at the same speed as Tsuna. Almost there, only a few more blocks.

"Ah um, I think Gokudera-kun said first period was postponed for a teacher's assembly..." Tsuna surmised, trying to remember what the reason was.

Suddenly, the world started to spin around Tsuna. The brunette felt lightheaded and dizzy. Colors spun, lines and objects merged and blurred together and a sickening nausea filled Tsuna. It felt like he had been hit by the ten-year bazooka and was flying through that weird color light tunnel thing.

"Tsuna-kun, are you ok?" Enma questioned in concern.

Then the dizziness faded away. Only a slight ringing in Tsuna's ears and an achy sensation remained. Enma stood there a few feet in front of Tsuna, with a concerned expression sprawled across his face. Tsuna realized himself must have stopped running when the dizziness took him over.

"Yeah it's nothing. I... um... thought I felt something but it isn't here..." Tsuna lied; he didn't want Enma to worry over him as well. "Anyways let's go. I don't want to be late..."

"Um... whatever you say I guess..." Enma complied, confused and uncertain. So they started to chase after Gokudera and Yamamoto, who hadn't noticed what happened.

Tsuna fell asleep during class. The brunette tried to stay awake, he really did try. But Tsuna could feel his eyelids growing heavier and heavier with drowsiness as the minutes ticked on by. The young decimo tried to distract himself by seeing how his friends were faring. First the brunette glanced at Gokudera; the Italian was scribbling furiously in a notebook, most likely in his own G script. Turning his head slightly, he noticed Yamamoto and Enma both napping peacefully. Like the latter, Tsuna decided to join them and succumb to his sleepiness.

He slept through that class and the next and the next. Eventually the lunch bell sounded, but the noise could not stir the sleeping Vongola.

"Wow~ Tsuna must be really out of it! Even the teacher wasn't able to wake him up!" Yamamoto observed, poking Tsuna's cheek in some attempt to wake up Tsuna. It was to no avail.

"Oi don't touch Juudaime! If he wants to sleep, let him!" Gokudera complained loudly.

"Haven't you noticed? Your banter usually would wake him up! The teacher would have been able to stir him...I wonder what that kid has been putting him through?" Yamamoto wondered, brushing the bangs out of Tsuna's face. The slumbering teen didn't even flinch.

"Hmmm yeah you're right but why? I mean he complains he's tired all the time and falls asleep in class regularly, but not to the point where he's dead to the world in class..." Gokudera started pondering as well.

"Hmmm maybe it's because of this...?" Enma suggested, pulling out an aspirin pill container out of the pocket of Tsuna's winter jacket.

"Why did Tsuna need to use extra strength aspirin, didn't he know the main side effect was drowsiness?" Enma tilted his head with confusion.

"Eh?" Yamamoto and Gokudera inspected the container. There it was printed on the label: Extra Strength Aspirin. Main side effect: Drowsiness.

"Didn't Juudaime say he took non-drowsy Aspirin?" Gokudera sweat dropped; sometimes his boss was too absent minded.

"Ha ha~ that's Tsuna for you!" Yamamoto chuckled, as he heaved the sleeping teen slung over his shoulder.

"What are you doing to Juudaime?" Gokudera screeched with fury.

"Maa maa, weren't we going to eat on the roof? We'll just bring this sleepyhead with us! Yo Enma, feel like joining us?" Yamamoto smiled while Gokudera fussed over the fact Yamamoto was touching his precious Juudaime.

"Sure. I've got nothing better to do... besides Tsuna-kun..." Enma muttered, too shy to admit he was worried about the brunette.

"Of course," Yamamoto understood. The rain guardian understood Enma and Tsuna shared this weird connection thing, it could be because of their descendants bond or just that they were so alike and could relate so well with each other. Yamamoto ruffled Enma's hair with acknowledgement. "Come on let's go!"

"Oi Baseball freak! Don't make decisions for us!" Gokudera whined. They headed upstairs towards the roof.

"It'll be nice!"

Tsuna awoke to light tickling sensation brushing across his face. Dragging his eyes open, he noticed soft red hair brushing against his face.

"Ah you're awake, Tsuna!" Enma noticed, tilting his head down to peer down at the sleepy brunette. Tsuna realized it was Enma's soft hair tickling his cheeks and that the young Vongola had apparently been leaning heavily on the Shimon Decimo's shoulder.

Tsuna sluggishly sat himself up, letting his messy almond colored bangs fall into his eyes. He lazily tried to brush his bangs out of his face, but Enma beat him to it. The redhead also took the cuff of his sleeves and dabbed the drool off of the corner of Tsuna's mouth.

"Hnn... Enma...? Weren't we just in the class room?" Tsuna yawned, looking around in a daze.

"Yo sleepyhead! We were, but you decide to take a long nap!" Yamamoto laughed from where he was sitting and eating his lunch.

"Wah...? Aw man! Why am I so drowsy?" Tsuna whined, attempting to rub the drowsiness out of his eyes.

"Good morning Juudaime!" Gokudera greeted with enthusiasm "You're drowsy because you accidently took the extra strength aspirin!"

"Hiiiieeee! I did? Of course I'd do that! Aw man..."Tsuna cried, trying to stifle a yawn and rub the sleep out of his eyes at the same time. At least his headache disappeared, and the pain in his muscles lessened.

"Maa maa~ it should wear off soon!" Yamamoto explained, patting Tsuna on the shoulder in sympathy.

"You should be more careful with extra strength aspirin, Tsuna-kun!" Enma advised quietly, fidgeting with the cuffs of his uniform.

"Ah I'm sorry to make you worry, Enma-kun. I promise I'll thoroughly check the label next time." Tsuna promised, already starting to feel a little more awake.

"Hmmmm. Juudaime, maybe you should ask Reborn to pass on training today. I've been doing some calculations," Gokudera pulled out a whiteboard seemingly out of empty air. The board had scribbles and charts on it that neither Tsuna, Enma, or Yamamoto could understand.

Where in the world did he get a white board from! And when did he have time to do all this?" Tsuna stared with awe at the intelligent white board.

"See this here..." And Gokudera went off into a whole super complex, intelligent explanation of the contents drawn on the white board. All Tsuna really noticed was an eerily looking figure of him drawn in erase markers on the board. All the other things he said just kind of blurred together and he didn't understand a word of it. Oh, there was that irritating headache again. Great.

Enma raised his hand, "Gokudera-kun, I don't understand!" Enma bluntly stated, nearly in a Fran like voice. Tsuna glanced towards Enma thinking: He's a brave kid.

"Dame-Enma! Have you even been listening to a word I said?" Gokudera loudly inquired, striking the white board with a pointer in emphasis.

"Haa haa~ He's trying to explain that with Tsuna's overall body weight, outweighs the amount of tablets he took and how potent the side effect of drowsiness in Aspirin. Therefore the Aspirin couldn't have been the only variable in causing Tsuna to feel exhausted and fall asleep during class." Yamamoto chuckled as he explained in one sentence what Gokudera had been taking about for roughly ten minutes.

Tsuna and Enma's jaw nearly dropped. How in the world did Yamamoto understand that? Gokudera featured a similar expression of shock.

"What ~? It was obvious from the squiggles on the white board!" Yamamoto nodded like it was the most sensible thing in the world. Tsuna sweat dropped. It was such a Yamamoto thing to do.

"Anyway, please don't over-work yourself Juudaime..." Gokudera warned, unease filling his green eyes.

"It'd be better to ask Reborn not to over work me... I wouldn't mind a day away from training though," Tsuna sighed; his subconscious knew it would never happen. The arcobaleno was too eccentric for that.

"Maa maa~ I'm sure if you explain the situation to him, the kid would understand!" Yamamoto advised with sympathetic eyes.

"It never hurts to try... well then yet again in Reborn's case..." Enma muttered.

"Ah well I'll ask..." Tsuna hesitantly stated, running a hand through his hair in nervousness. The brunette knew the answer already though; Reborn would never let him get a day away from training.

"Ah that's the class bell; we should go..." Enma mumbled, as the loud bell rang through the hall ways and on top of the school.

"Hmmm yeah."

With that, they were off for another exciting afternoon of classes and torture.
