Chapter One

Age: Two

Tsuna stared at Reborn while breathing in and out. His head has been nagging at him since morning. He doesn't know why, but it's nudging him towards his spartan tutor. And now that he realized, Reborn isn't himself.

The infant is a little flushed. He's sweating alot and has this almost invisible contortion of discomfort under his usual stoic face. He's glare are still there, but the intensity is wavering. It feels like Reborn... Is not okay.

It been a month since Tsuna freed the arcobalenos from the tri-ni-sete curse. Lal is in the CEDEF, working her ass off with all the exercise she missed with her body. Colonnello is with her. Fon is in China. Skull is somewhere, so is Verde while Mammon is in Varia. Aria is in the Giglio Nero, attending her duties as a boss and a mom for Yuni. And Reborn is with Tsuna, doing all the sadistic things he can thought off.

Tsuna sat up and dodged a bullet when Reborn fired. He held his hands up, the baby raised an elegant brow at that.

"Can I talk to you like for five minutes before you train me again?" Tsuna asked with cautiousness.

"We are already talking, Dame-Tsuna." Reborn replied.

Tsuna blinked. "Uh..."

"What?"

"Are you okay? You're flushed and sweating too much." He asked immediately, worry evident on his tone.

Reborn tutted. "Do you want me to put a lead on your head?"

"No, Reborn. Be honest with me." Tsuna said as he stood and neared the baby. "Are you okay?"

"Why won't I be?"

"My head is nagging at me that you're lying."

Reborn glared at him. "It's none of your business, Tsuna."

Tsuna sighed. "It's the curse right? Your body is getting ready to be stretched or something."

"And how the hell did you know that?"

"Cause you taught me that much." The brunet said before picking up Reborn who pointed the barrel of the gun at him. "Relax. We're going home."

Reborn huffed and let Leon turn into it's original shape. The chameleon crawled to his shoulder and leaped to his hat. Tsuna started to walk out of the forest they were in. Feeling worried and wanting to comfort his tutor, he unconsciously let some of his flames out. Reborn sagged in his arms and Tsuna got worried even more.

He sped walk towards their house. The moment he got in their compound, he started to panic and opened the door. He announced his arrival and went straight to his Mother.

"Kaasan! Reborn is not feeling well!" Tsuna said with fright in his voice.

"Eh?" Nana blurted out and went to them. "Let's see."

Tsuna watched as his mom check on Reborn who was breathing a little too deep to his likings. His mom pressed her hand gently on the hitman's forehead before placing it under his neck. Nana looked at his worried son, and smiled reassuringly.

"He got a little fever. Place him in your bed and change his clothes, okay? I'll get water and some things to ease up the heat." She instructed.

Tsuna nodded with resolve. "Hai Kaasan."

Nana watched his son walked out of the kitchen before smiling fondly. "Ara... Tsu-kun is all grown up."

Tsuna went inside his room and place Reborn on his bed really gently. He went for his closet and rummaged inside for clothes that his tutor can wear for the meantime. He kept on repeating his mom's instruction inside his head.

Place Reborn in the bed.

Change his clothes.

Tsuna got a small shirt and a shorts. He went to Reborn's side, put the latter's hat on the side table gently not to hurt Leon and was about to remove the baby's suit when Reborn's eyes opened. It was alert and frantic. A side Tsuna yet to see.

"Reborn? Hey?" Tsuna called out softly and careful.

"Tsuna..." The hitman whispered.

"It's okay. It's me. Mom checked you and she told me to make you comfortable. I'm taking your suit off so I could change your clothes. If you want Leon, he's here."

Reborn didn't say a reply.

Tsuna went on with his task. "I know you hate this but bear with me? It's much better than being alone."

"I'm gonna triple your training."

Tsuna shrugged as he gently pulled the coat off of Reborn. "I don't mind. So long as you get better, I'll even rile you up to quadriple it."

"Huh." Reborn managed to smirk.

"Reborn." Tsuna called softly. "I want you to be honest with me when you're uncomfortable, okay?"

"You're gonna spoil me if I do."

"I will if it makes you feel better."

Reborn didn't talk again and watched Tsuna make him wear a blue shirt and fold his upper attire into a neat pile on the side. He was changed out of his pants too and wore a pajama bottom that snugged on him. He watched his student neatly fold his clothes and put them on the side table, underneath his fedora. Then he felt a warm fluffy blanket being placed on him.

Tsuna contemplated but he remembers how his Kaasan do it and makes him feel comfortable. So he did. He sat crossed legs on the floor, and carefully ran his hand on Reborn's hair. At first, the infant stiffened, but after awhile, he relaxed and closed his eyes. Tsuna started to hum, getting a little comfortable and less worried.

"Tsu-kun?" Nana called, walking in with a basin of water and a small towel hanged on the side of it.

"Kaasan." Tsuna smiled.

"Here are the things. I'm making soup so Reborn-kun can at least drink before giving him some syrup for the cold." The brunette informed while putting the things she has on the small table in the room.

Her son paled. "Y-You're not gonna take care of him?"

"Oh." Nana smiled. "It's time for you to take care of him in return, Tsu-kun. Reborn-kun took care of you up until this morning, so you have to reciprocate right?"

Tsuna bit his lower lip, considering, before nodding. "Y-Yeah."

His mother smiled. "Okay. I'll call you when the soup is ready."

"O-Okay. Thank you, Kaasan."

Tsuna watched his mother go before taking the basin to place it near him. He soaked the towel on the warm water that smelled like alcohol, wrung the water, folded it then placed it on Reborn's forehead. His brow furrowed a little when the little hitman whimpered. Tsuna took his little hand and gave a small squeeze. Reborn squeezed back with a small cough.

"Reborn." Tsuna called softly, worry coming in at full force. "Rest. Kaasan and I will take care of you."

"That doesn't assure me of-" Reborn coughed again, Tsuna gently rubbed the baby's chest. "-anything good when you're in it."

Tsuna faltered. "O-Okay. I'll tell Kaasan that you want her to-"

Reborn squeezed his hand. "Shut up Dame-Tsuna. And what did I say about stuttering?"

"Hai."

Nana hummed as she poured the soup on a bowl on top of a tray. When she called out for Tsuna, her son immediately came down, not even tripping on one step and came rushing towards his room after saying thank you. The matriarch smiled pleasantly at the show of affection her son is trying to convey. She knew her son is never good at things, hence his nickname Dame-Tsuna. But now that he's fifteen, he can do simple things like chores and stuffs that can help her thanks to Reborn's tutoring.

She is in debt of the small teacher who made her son strive so hard when she, herself, can't do.

Tsuna contemplated where to sleep. He's used to the setting where Reborn is on his hammock while he's on the bed. He sighed, wishing Bianchi was here to help and take Reborn to her room to smoulder. The pink haired lady, also known as Hayato's older sister, is out of town due to an assassination job.

Tsuna looked at his closet before standing up. He took the futon out of there, with the extra blanket and pillow. He placed it beside the bed and laid down in there while facing his left. Knowing Reborn has taken his medicine after the meal before the brunet went down for dinner, he slumbered peacefully.

Reborn woke up in the middle of the night, cold and dizzy. He is not feeling well. His muscles are sore and every fiber of his body is in pain. He struggled to get up and looked around to spot his student. He grumbled when he didn't and about to jump down when he noticed the teen, sleeping with furrowed brows indicating that he's having a surreal dream. Reborn stared before jumping down and went near the brunet. Huffing, he went under the cover and laid beside Tsuna. The brunet reacted instantly, arranging Reborn so that his pillow is the Decimo's arm and hugged him by the waist.

Reborn sighed contently, feeling a little warm against the cold he's feeling. He doesn't care if Tsuna wakes up with him in his student's arms. He's the world's greatest hitman. He can do anything he wants. Even blame his dame student that the latter took him out of the bed to cuddle him.
