It started with barely heard whispers during a private party with the two Millefiore bosses, and the Inner Circle of the Vongola Decimo's generation.

Now, the whispers might not mean something if it were not for the words they heard from Tsuna and Yuni- which then was confirmed by Reborn.

Right now, Tsuna, Reborn, and Yuni were sitting on the couch, in that order. Tsuna looked around for any eavesdroppers while Yuni placed a hand on Tsuna's in an attempt to calm the older person down. Reborn stared at any potential eavesdropper with unblinking eyes. When Tsuna and Yuni established that no one would be listening into their conversation, they faced each other and started.

"… droopy and sad…" Yuni's whispering voice said.

"… right conditions… becomes erect…" Were the most curious and the most choking-induced words that came from Tsuna's equally soft response.

The words got everyone listening and both Yuni and Tsuna look at Reborn as if asking confirmation from the hitman. It looked domestic to the on-lookers, with Tsuna and Yuni being the children of Papa Reborn.

Everyone were unsure with what to do with the sudden mental image.

"Dame-Tsuna's correct," Reborn said, leaning back as he smirked at those who were trying to look like they weren't listening in, "Since we've improved a few things, it will be erect when you see it tomorrow." Tsuna and Yuni seemed to notice something and they started to giggle.

"If you say so, Uncle Reborn," Yuni said, her eyes twinkling as she looked at Tsuna, who grinned excitedly when he turned to Yuni, then to Reborn.

"So, want to try again tomorrow?"

Of course, everyone invested in the conversation were horrified, even more so when Reborn joined in by saying, "I volunteer to supervise."

Tsuna rolled his eyes (and fighting back a smile) while Yuni seemed to be giggling at something even more, "You've been supervising from the very beginning, Reborn," he said, "More like teaching at first, but you don't need to announce it when it's a given."

This horrified everyone more than Reborn's words just a few seconds ago.

Yuni burst out laughing while Reborn coughed once, trying to resist the laugh that was bubbling up in his throat. Tsuna cheekily grinned at the two with knowing eyes and then he stood up. "I'll go see myself out," he said as he gave them a mock salute.

'WHAT WAS THAT?!' Everyone but the three thought collectively.


Gamma was pacing. Hayato looked thoroughly terrified. Takeshi was nervously laughing. Ryohei was silent. Hibari was breaking things that Mukuro was all too happy to provide. Lambo wore a blank expression. Even Byakuran was just poking the bag of marshmallows in front of him. Well, basically, everyone were not acting like themselves (except for Hayato, Takeshi, and Gamma, their reactions were what everyone knew would happen).

"What is your boss doing to the Princess?!" Gamma said, finally unable to keep the question inside his mind.

"The fuck do I know?!" Hayato growled out, "I'm more worried about Tsuna-sama's chastity!" He punched the wall beside him and took a seat on a couch.

"That's what you're worried about?" Lambo interjected, eyeing Reborn and Yuni at the farthest and opposite corner of the room. "Because I'm more worried about Reborn's participation with… whatever they were doing." Lambo shivered, closing his eyes and covering his ears, "Oddio, please get the mental image out of my mind!"

Mukuro chuckled, "Oya, we just can't jump into conclusions," he said, "For all we know, they could be talking about another thing entirely." Hibari paused in his breaking things, looking up contemplatively.

"Possibly," Hibari agreed, taking a seat now and terrifying the rest of the group other than Mukuro, "But either way, I will bite the small animal to death."

Tsuna paused as he passed by them. He looked up, as though debating something.

Yuni and Reborn noticed him and looked at Tsuna expectantly.

"What else do you think 'droopy' and 'erect' apply to?!" Hayato asked, and blushed as he covered his face, "Fuck, now I am embarrassed for saying that aloud." Takeshi coughed and everyone sighed.

Tsuna grinned (one that would have reminded the viewers of a very mischievous Byakuran) when he finally came to his conclusion, "You can join us, you know," he said, gaining everyone's attention, "It's going to be fun!" He paused, watching everyone's expressions with a hidden glee. Good. It was now time to have fun with his wording.

"It's a stimulating exercise- makes you sweat from all the heat!" Tsuna exclaimed, ignoring Hayato and Gamma fainting from what he had just said. Takeshi caught Hayato in his arms before the Storm would touch the ground while a loud thud signified Gamma's landing. Lambo looked ready to faint, and Tsuna was amused that the teen could handle what he was saying better than the adults that were Gamma and Hayato.

"I still remember the first time we did it- we were all hot and sweaty after!"

There went Lambo, Ryohei and Byakuran. Mukuro coughed while Hibari glared at him. Tsuna winked at them.

"Anyway, I should go back to Reborn and Yuni," he sang, "We have to schedule for the next session after all!"

Tsuna laughed as he dodged a flying tonfa, running over to his fellow conspirators.

Reborn did influence Tsuna's sense of humour, while Yuni's sense of humour was a result from being with Tsuna, Reborn, and Aria.

Especially Aria.


"Tsuna-nii, how did it go?" Yuni asked when Tsuna got to them. Tsuna cackled as he took the empty seat next to Reborn.

"They're definitely thinking that we're doing something indecent now," Tsuna answered when he calmed down. He took two notebooks from within his suit and handed one of them to Yuni, "Victoria and Yang are doing well, too well. I can't keep them in my room anymore." He laughed nervously at Reborn's raised eyebrow. "I theorise that my Sky Flames somehow make them grow faster," he offered as he gave Reborn the other notebook.

"That's odd," Yuni said, a small frown on her face, "Mine makes Kali droop and there's some signs of burning on Sigma's leaves." She handed Reborn her notebook. Reborn took it and read it.

"It could be your Flame's secondary traits," Reborn mused, when he returned their notebooks to their respective owners. "Due to my Flame's secondary trait, my first few plants kept flowering." His eye twitched as he remembered the first few plants he had decided to grow. He gained the title Il Fioraio for a short period because the number one thing his clients and indirect witnesses remembered him by was the smell of flowers that followed him. It forced Reborn to abandon gardening and botany just to decrease the amount of witnesses to his hits.

Funnily enough, no one connected Reborn with Il Fioraio.

(Although, Tsuna figured it out a few weeks after Reborn agreed to teach the former how to garden.)

(A passive-aggressive Reborn was unleashed onto Tsuna for the next few weeks after the revelation.)

(Somehow, the passive-aggressiveness terrified Tsuna more than when his External Advisor was actively scheming.)

(Reborn made sure to abuse that information whenever he was pissed at the Vongola Decimo.)
