Hibari set the report on his boss's desk, "I'm done." He turned to head back to his quarters.

"Thanks for your hard work, Hibari-san." Tsuna smiled in gratitude, taking the paper and signing it. "Oh and…Dino-san's here."

"Haneuma? What is he doing here?" Hibari raised his eyebrow in confusion.

Tsuna smiled again, though it was not as sincere. "I think he wants to meet you. This mission kept you away from him for three months, after all."

Hibari's expression never changed, except for a light twinkle of amusement in his eyes, "Hmm…I assume he has done something stupid again?"

Tsuna laughed lightly, "Other than falling down the stairs and breaking a few vases? Nope."

Hibari turned and walked away, "Then I will see him before going back."

Tsuna watched as Hibari excited his office, whispering, "Have fun…"

Tsuna leaned back on his chair, releasing a long sigh. He really needed to stop feeling like this towards his Cloud Guardian. His Cloud Guardian already found someone that was fitted for him. And he, the 'No Good Tsuna' is nothing compared to Dino Cavalone. True, he managed to inherit the strongest mafia family in the world, the eight strongest and deadliest people in mafia world are his Guardians as he grew up, but...though he was the Tenth Vongola Boss and worshiped by all, he didn't have even a portion of the Tenth Cavalone Boss's self-confidence.

He always admired the man named Hibari Kyoya. Aloof and walking on his own path, so strong even without anyone by his side. Yet in that cold heart, there existed a kindness hidden deep within. Many times they were saved by his strength in many hard battles. He will always admire and love him, even if the man didn't show any feelings towards his boss, and he is satisfied with their relationship now.

He looked at the photograph on his desk. That was the only photograph of all his original family members together. He missed those times when he could just fight along with his friends to protect their time together. Now, he had to fight to protect his family that kept getting bigger and bigger each day passed by. And he still needed to fulfill the Primo's expectations of him. He didn't have time to hope for something that would never come true.

His eyes wandered to a certain person in that photograph, who stood the farthest from his Cloud Guardian, yet he still managed to see the rivals glare at each other. He let a chuckle out, "And he hasn't realized what his heart wanted the most yet..."

He can only hope that when the time comes, only he will feel the heartbreak. He doesn't want his Mist Guardian to lose the heart that he finally got back after so long living without it.

Everyone in the Vongola and Cavalone, even the other families, had known about the relationship between the Cloud Guardian of the Vongola and the Tenth Boss of the Cavalone. Sure it had taken ten years and many hardships in Dino's part, but he finally managed to capture Hibari's heart. Though Hibari will never show his affection towards Dino in public, the Bucking Horse had already done his share. They were suited for each other, and no one had ever judged their relationship. Tsuna made it know that he wouldn't forgive anyone who judged their relationship either.

"Oya? So you're still alive. I thought that because you were not here for such a long time, you had died on your mission." Hibari groaned when he heard his rival's voice.

"Unfortunately for you, I'm still alive." The skylark glared as Mukuro revealed himself from his hiding place, covered with mist.

"It's fortunate for me too, Kyoya. I would be bored to death without you around." His playful smirk only further irritates the Cloud Guardian and he knew that. "Do you want to spar? I'm free at the moment."

The temptation to punch that infuriating face was almost too great to pass, but he still had things to do. "Not now, illusionist. I'm busy."

Amused, the Mist Guardian replied, "Oya? The fearsome Hibari Kyouya backed down from a fight? Looks like the world is nearing it's end, kufufufu~"

Hibari was tempted to use his box weapon on Mukuro, and he almost did it if not for a voice calling him, "Kyoya! You're finally home!"

Mukuro and Hibari looked towards the running blonde coming their way. "Kyouya! I missed you so-gah!" Dino tripped on his own feet, his face hitting the floor hard.

Mukuro's smirk disappeared from his face, a rare thing to happen. "Oya, oya…so this is what's keeping you busy."

Hibari sighed as he looked down towards the groaning Cavalone, "Stop being clumsy or I'll bite you to death."

"It's a permanent thing, I guess…" Dino laugh sheepishly. "But I'd be alright if I had my family around! Why am I still like this even when I'm with you?" He grumbled childishly as he stands up from the floor.

"I am not one of your men, Cavalone." Hibari turned to warn Mukuro from making a comment, but to his surprise, he couldn't find him anywhere.

"Ah, that's right," Dino's voice taking his attention back, "I want to talk about something…"

"Mukuro-sama? What's wrong?" Chrome's shy question brought his attention back. He was using his illusions to search for entertainment, bored without Hibari around until he found the skylark and was about to have a good time before Dino came.

"Nothing, my dear Chrome," he looked at Chrome, looking at him with worried eyes. "I'm fine, why are you asking?"

Chrome hesitantly answered in a small whisper, "Your face looked so sad for a moment. What happened?"

Mukuro was surprised, not only at Chrome's question, but at himself as well. Since when was he capable of showing such emotion?

Chrome wasn't sure if this was a great time to tell him, but she did anyway. "Mukuro-sama, have you heard the news?"

"What kind of news, Chrome?" Mukuro tried to control his own surprise once again, since had lost his emotions in his third time living. But now, why did he have it again? After so long?

"The Cavalone Boss is going to propose to the Cloud Man."

Mukuro did not know what made his heart shatter into tiny pieces.
