So I know I haven't updated my other fic in 4 months but... still

When Tsunayoshi first stepped into his new apartment, he was ready for a nice, calm next few years with his neighbors - that he probably wouldn't ever see in his opinion. But he definitely wasn't ready for what was to come.

The short brown-haired male huffed in the summer heat, sweat rolling down his forehead in beads as he traversed the grounds with boxes in his hands. Once he had left college, his mother, Nana, had recommended the apartment complex to him. She said it was a friendly and peaceful area to live in that not everyone could get into. Tsuna was either very lucky, or this was one hell of a coincidence. On a waitlist of over five hundred people, Tsuna just so happened to get into the heavily restricted M. Residential Apartments.

How? He did not know. But he was glad nonetheless.

Flicking up the card he had been given to find his new apartment, he read over the words to make sure he got the right house.

M. Residential Apartments

Tsunayoshi Sawada

Sector: Vongola

Apartment Number: 27

He kicked open the door with the back of his foot, bringing in one of the heavier boxes before setting it down away from the door. He repeated this process until he was around half way done, but hours had already gone by. It was just him moving boxes so it went exceptionally slow. Taking a small break, Tsuna downed a water bottle while gazing over the other apartment windows. Lingering on one of them for no reason, in particular, he noticed the blinds ruffle open, and green eyes narrowed at him, almost as if analyzing him. Tsuna looked around to make sure there was no one else, before snapping back up to the window. Furrowing his brows, he glanced around before looking back to the window with the person looking down at him.

When he noticed the blinds flutter closed, the young man just shrugged and went back to transferring boxes.

It took quite a few hours, but Tsuna had finished transferring boxes and was around halfway unpacked. After he had unpacked most of his consumables, he went about making a nice cup of tea during his break before unpacking the rest of his boxes and putting together all his furniture - it was at this point he wished for an instruction manual.

All was silent and calm, giving Tsuna a moment to breathe. Sipping his tea, he felt his senses calm and a small smile curl on his lips. Maybe later, he would go and introduce himself to his neighbors. He hadn't met them yet, but since there hadn't been any disruptions or calamities at all, Tsuna felt that they were going to get along splendid-

"VOOOIIIIII!"

-ly.

Tsuna nearly cracked the teacup in his fist from shock.

It was silent for probably three seconds before the whole room shook. Loud bangings on the brown-haired male's door sounded throughout the entire complex. Each 'knock' - more like smash, Tsuna's mind supplied - was rougher than the last.

"Voiii! Neighbor! Open the damn door!"

Tsuna, for a moment, contemplated not opening the door.

But that wouldn't be polite. And would probably lead to his death.

Shuffling to the door as the bangs and yells grew louder, Tsunayoshi braced himself before swinging the door open. In front of him was only describable as a shark with - beautiful?- hair.

"Can I… ahem, help you ma' - sir. Sir." Tsuna quickly hid his blunder of calling this… thing a female

It's the hair, isn't it?

The man's expression suddenly morphed into his own form of awkwardness before it went back to the normal fierceness. "Right, right. I was making tea and needed some sugar. I was out so I did the only thing I thought of was asking my- why am I telling you this- Ah fuck it. Just give me some sugar." He growled at the end of the mini rant, crossing his arms self-consciously, and blowing a strand of silver hair away from his eye.

"Ah, well you see-" Tsuna began to explain he hadn't yet unpacked the sugar yet - he wasn't actually sure where the sugar was packed - when his neighbor interrupted once more.

"I don't care, just give me the damn sugar, trash."

The small brunet was suddenly offended before he sighed and opened his house to the rabid man. "Well I would love too, but I have no idea where it actually is."

Needless to say, the man - Squalo was his name apparently - ended up helping Tsuna unpack the best of his boxes and the two were done within the hour.

He still never found the sugar.

Dragging a hand down his face, Tsuna compromised with the livid man. "Okay, how about his? I'll go out and buy some sugar later today and you can come over and I'll treat you to tea. Sound good?"

Squalo tsked and looked away. "Whatever scum." He was about to slam the door shut before facing Tsuna once more. "I'll be over by noon."

Shutting the door with a soft click, Tsuna began to contemplate his life decisions about moving to this new apartment complex.

Maybe it won't be too bad?

The building shook from a shout across the hall.

I regret everything.

Tsuna decided just to deal with it and go get his cat so they could deal with it together. He had left Natsu with his mom for the weekend as he moved into the apartments and he would need to stop by to get the little creature.

At least someone will know my pain.

Elsewhere in a dark apartment, silver hair held into a miniature ponytail, a conspiracy theorist watch the brunet leave the complex and drive away in his car. Pictures of the fluffy haired male were strewn across the walls with red yarn connecting the multitude of pictures.

"Soon," he chuckled darkly, a grin on his face. "Soon…"

And then he promptly tripped on one of the other apartment residents cats that snuck into his room. "Son of a-"

Tsuna never knew what was coming for him.
