So, a quick note before this starts. The prologue is up! It's called Connections (: It's posted as a separate one-shot, so check it out afterwards? *grins* Remember to review!

Siblings

"Tsu-kun, I have some news for you."

Tsuna tilted his head in confusion and looked to his mom. She giggled slightly before taking a deep breath and looking at him seriously.

"Do you want a little brother?"

Tsuna blinked once, silent. Then he blinked again before the news finally settled in. He jolted out of his chair, hands accidentally knocking over his mug.

"Eh? Mom, are you pregnant?" He blurted out without thinking, ignoring the mess that was now on the table and dripping onto the floor. Nana grabbed the dishcloth from the kitchen counter and wiped up the mess, unperturbed by Tsuna's reactions. Aware of her son's disbelieving looks and growing irritation, she looked up and smiled reassuringly.

"One of your dad's friends was in an accident. The entire family died in the car accident, leaving behind a small child." Nana stopped there, carefully observing Tsuna's reactions. Tsuna furrowed his eyebrows in concentration, trying to not allow the surge of sympathy and empathy show on his face.

"How long have you guys been thinking about this?" He finally asked, feeling more rattled than his outward appearance suggested. Nana looked at him, unable to fully read her son.

"Ever since the night of the accident. The child... Isn't very well liked by the rest of his relatives." She said carefully. He closed his eyes, feeling the sympathy rise up further. Tsuna picked up the cup that he had knocked over and set it on the table, sitting down. Nana didn't move from her position.

Finally, Tsuna looked at her and smiled warmly. She felt a large amount of pride blossom and surge in her heart as she walked over and pulled her son into a tight hug.

He hid behind the big person's leg. He was suddenly brought to a weird place and he didn't understand why he was brought here. He wanted to go home!

"It's ok." He looked over timidly and a smaller big person with kind eyes smiled at him. He didn't know why, but his heart immediately calmed down and he found himself drawn to him. He took a cautious step forwards, big round eyes looking up.

"Who are you?" He asked shyly. A gentle hand patted his unruly curls.

"I'm Tsuna. I'll be your big brother from now on." Ah, that's why. That's why this person felt so safe.

"Big brother? You're Lambo's big brother?" Big brother picked him up and grinned. He automatically wrapped his smaller arms around big brother's neck and snuggled in.

"Yes, yes I am."

Note: Lambo's perspective is so hard to write… I think any child's perspective is hard to write, tbh. You have to make sure not to use big words -_- But, THEY ARE ALL TOGETHER. This time, for real. XD

So, now that's everyone's together, where are they headed? Stay tuned for more Vongola Decimo fluffiness~!

Also, maybe you'd like to check out the prologue? Just saying… hehe. Please review!
