Hey everyone!

Yep, I'm back! To those of u who have been waiting for an update on my last BH6 fic, Please, Forgive Me, sorry for not updating it for a while as I've been in a writer's block on it. :( Please feel free to pester me with ideas through PM.

This is a REWRITE of my first BH6 fic, Sick Hiro. Felt the previous one was messed up with a lot of grammar mistakes. Now this version is better, much more detailed, and even FLUFFIER. :) Thanks to those who favorited, followed and reviewed it. It meant a lot to me. If u loved it, I'm sure u would love this longer version even more.

Thanks to Forever-Tangled for beta reading it for me.

I don't own Big Hero 6.

Hiro Hamada coughed outrageously. His nose was running, which was burning like hell, and his eyes were tearing. Also, his cheeks were flushed. A thousand of used tissues were scattered on his bed, which indicated how bad his cold was. It was 5am (basically morning!), and he hadn't slept a wink since. God, he just did not feel good. How he had wanted to go to sleep! But every time he laid down, his runny nose would just get worse and he'd have to sit up to blow.

"Stupid cold," he murmured, feeling frustrated, as he grabbed a bunch of new Kleenexes for, like, the millionth time. As he was blowing his nose, he suddenly felt the urge to cough again. Trying not to wake his older brother, Tadashi up, he tried holding it in, but failed. Tadashi was in his side of the room, lying on his side, snoring lightly. Hiro coughed and coughed into his fist. Please don't wake up, please don't wake up, he kept thinking.

"Hiro."

Great. Just as he had expected. He berated himself for not being strong enough to hold his cough. His damned cough.

"Yeah, Tadashi?" he murmured.

"You alright, baby brother?" Tadashi asked, as he pushed his blankets back and sat up.

Hiro thought of answering him with an "I'm fine" but then, deciding that he couldn't hold his cold any longer, whimpered, "my nose is burning, and my throat hurts like hell."

Tadashi, big brother instinct kicking in, stood up quickly and was at his younger brother's side in an instant. He felt the back of his hand against his forehead.

"You're burning up," Tadashi said, a hint of worry in his voice, as he moved the used tissues out of the way and sat on the edge of the bed. Feeling sorry for his little brother, he reached out and hugged him tightly. "Oh, Hiro," he murmured softy, as he stroked his raven hair. "Why didn't you wake me up?" He was guilty for not noticing his younger brother's illness earlier.

Admittedly, Hiro was feeling a little glad his brother woke up as he knew Tadashi always knew what to do. He shrugged. "Sorry, just didn't want to bother you."

"Hiro, you know you should never hesitate if you need anything. Now let's get you a thermometer…" Tadashi said, as he stood up and walked over to their washroom, which was on the far side of the room. Before he went in, he glanced back at his younger brother. "Meanwhile, lie down and stay awake, alright?"

"Obviously I'll be awake. There's no way I'm able to sleep, anyway," Hiro muttered to himself as he laid down just to sit up quickly to blow his nose.

Within minutes, the older Hamada came back with the thermometer.

"Open up," Tadashi urged his younger brother gently, who reluctantly opened.

He slowly took out the thermometer and cursed when he saw the temperature. 102.

He looked back at his younger brother, who was staring back at him.

"Oh Hiro," Tadashi said softly as he gave his younger brother another hug. "You're having a really bad fever."

Hiro just rested his head on his older brother's chest, enjoying the warmth Tadashi's giving him.

Tadashi pulled away a little as he felt his younger brother's forehead again. "Want some tea?" he asked softly.

Hiro shook his head. He wasn't in the mood for tea. All he wanted to do was try to go to sleep.

"Oh, come on buddy. Trust me, it's good for your sore throat."

Hiro shrugged. "Okay," he murmured.

Tadashi smiled. "I'll be right back, bonehead."

Within minutes, the older Hamada was back with a small mug of tea. "Here," he said, as he gently and carefully handed it to his little brother, who took it as carefully.

"Thanks," Hiro said, as sipped it little by little. He enjoyed the warmth it gave to his sore throat.

After that, Tadashi gave him two tablets of Tylenol to swallow. Hopefully, it would stop his coughing.

"Are you ready to go back to sleep now?" His older brother asked as he held up the blankets to tuck in his little brother.

"You know what," Hiro muttered. "I didn't even sleep."

Tadashi, who was always concerned for his little brother's well being, became immediately worried. "Oh my God! You were awake all that time?"

Hiro nodded. "I couldn't sleep, and I don't know if I will be able to now."

Tadashi quickly walked over to their cupboard. He grabbed an extra blanket, which he gently wrapped around his little brother before holding him like a baby, and walking over to his side of the room. He sat on his bed, his back leaning on the headboard.

"What are you doing?" Hiro asked as he squirmed, confused.

"Shhh… just close your eyes," Tadashi said gently, as he pressed his younger brother's head against his chest, and began rocking him.

Obeying his brother, Hiro closed his eyes, snuggling deeper into his chest.

"That's it," Tadashi murmured, as he continued rocking him to and fro.

The rocking motion seemed to be relaxing to his little brother as a small yawn escaped from his mouth, and he was slowly drifting off.

After an hour, when his younger brother was finally sleeping deeply, Tadashi carefully stood up as not to wake him, walked to Hiro's side of the room, and gently placed him on his bed. He slightly adjusted the blankets, tucking him in warmly. Tadashi smiled at the sight of his sleeping brother, remembering him when he was a baby.

"Sleep tight baby brother, and get well soon," he said as he leaned down and moved a strand of hair from his eyes before he went back to his side of the room.

Ahhh, the fluffiness! I melted all the way while I was writing it. :3
