They'd been in their new house for all of two hours when Reborn and his student came knocking.

The living room and kitchen were still a mess of boxes, and Hayato was currently in the room that was to serve as Shamal's home office, which his guardian had decided had to be the absolute first thing to be set up.

Perking up as the sound of the doorbell rang throughout the house, Shamal met Hayato's gaze.

"That's probably Reborn and Tsunayoshi-kun," he said. "Mind getting that for me, brat?"

Hayato's brows furrowed slightly as he looked up from the books he'd just finished arranging on the bookshelf. "Why the hell should I get it, old man?" he asked, crossing his arms stubbornly. "They're your guests!"

Shamal raised an eyebrow. "I need to go over Tsunayoshi's file one more time; and I'm sure that being greeted by someone else his age will help him relax so he doesn't get too worked up before our meeting."

Hayato glared at the doctor, not liking his answer, but at Shamal's insistent expression, he got up with a huff and left the room.

Already, the young Vongola's life was taking priority over their own, and Hayato was unhappy, to say the least.

Clomping down the stairs moodily, Hayato threw open the front door and glared at the first person his eyes landed on. He was puny, the brunet standing on their porch, and his features delicate and effeminate; exactly the kind of man girls loved.

Hayato hated him instantly.

He was still dressed in his school uniform – black slacks and a gakuran too big for his tiny frame – and he flinched away the moment he met eyes with Hayato, whose impression of the Vongola heir was plunging to lower depths every second he was in his presence.

The boy stuttered for a few moments, hands going up to tug at a strand of chestnut hair and seeming uncommonly surprised at what they found.

Before Hayato could spit scathing words at the coward on his doorstep, an infant appeared on the other boy's shoulder, slapping his hand away from his hair and giving him a pointed look.

The boy immediately dropped his hand.

Turning those coal black eyes back on Hayato, the corners of Reborn's mouth pulled up into a smirk.

"Gokudera Hayato," he acknowledged with a nod, and Hayato hastened to bow respectfully to him.

"Reborn-san," he greeted. Even if he had a bone to pick with his student, Hayato had nothing but the utmost respect for Reborn. "Please, come inside."

Stepping aside to let the hitman and his student enter, Reborn moved to close the door behind them, not bothering to follow them upstairs, knowing already that Shamal wouldn't allow him to sit in on the meeting.

Something about patient confidentiality.

The stupid doctor really did choose the strangest things to be a stickler about.

Standing there in the foyer, Hayato glared holes into Sawada Tsunayoshi's back right up until he and Reborn rounded the corner, and were greeted with Shamal's faint voice.

Rolling his eyes once more in their general direction, Hayato turned to start unpacking their kitchen.

As the door to the office closed behind them, Tsuna did his utmost to look everywhere but at the man standing in front of him.

Whereas the rest of the house was still full of unpacked boxes, crowded and still quite impersonal, the office was already completely set up, shelves crammed full of various medical textbooks, files spilling across the desk the computer sat on.

The walls were the standard off-white, mostly bare save for a few awards and certificates, and even one picture of the doctor and the scary boy who had answered the door, the one who had kept glaring at Tsuna.

He wanted to reach up and feel his hair again, still marvelling at how light his head felt now that he'd been allowed to chop off all his waist-length locks and refusing to think of how livid his mother would be when he arrived home.

But Reborn's earlier warning was still fresh in his mind, so he fiddled with the hem of his gakuran instead.

"I'm going to need you to take a seat now, young Vongola," the doctor's voice said then, interrupting his inspection of the room he was in, startling him.

Hurrying to do as told, Tsuna lowered himself into one of the chairs at the desk, and finally turned his eyes on the doctor.

He was a relatively young man, his dark brown hair hanging just to his shoulders and his cheeks dark with barely there stubble. His eyes were hooded, almost lazy-looking, but observant, drinking in every detail of a scene in seconds.

Tsuna felt, quite distinctly, like he was on an observation table, and he had to fight not to squirm.

After a few moments of staring, the doctor sighed and leaned back.

"I'll have you know, it's my policy to treat only women," the doctor informed him then.

At those words, Tsuna felt something unpleasant twist in his gut – he'd thought that here at least, with the doctor that Reborn had introduced him to, he would be safe, but evidently he'd been wrong.

He looked down.

The doctor heaved another sigh and ran a hand through his hair.

"But I suppose if I were to make an exception for anyone, it would be Vongola's heir."

Tsuna's head snapped up at these words, and he gaped.

The doctor was looking at him with a clinical expression on his face, all stern professionalism.

"From now on, should you ever need medical attention, you are to come to me, and me alone," he informed Tsuna in a severe voice, leaning forward with his elbows on the table. "I am unable to start you on your hormone treatment until I have had you as my patient for a bare minimum of three months, but once we do start, it will affect any and all medications prescribed to you in the future. Assuming your tutor will want to keep your…circumstances under wraps until you've better established yourself in your new position, this will also reduce the risk of you being revealed before you are both ready. Civilian doctors, after all, can be bribed."

"And mafia doctors can't?" Tsuna blurted out before he could stop himself.

There was a moment of stunned silence after his words, and Tsuna clapped his hands over his mouth horror welling up within him and wishing he could snatch the words back.

Then suddenly, surprisingly, the doctor let out a bark of laughter, seeming amused, and even Reborn was smiling from where he was sitting cross-legged on the desk.

"There's a reason I chose Shamal as your doctor, Dame-Tsuna," the infant informed him. "He may be a pervert, but he takes his job seriously, and he'd die before he violated a patient's confidentiality...not that anyone would be suicidal enough to threaten him in the first place, given he's one of the most notorious hitmen out there."

"HHIIIIEEE! HE'S A HITMAN?" demanded Tsuna, voice going too high-pitched in his surprise.

Reborn smirked widely.

"And he's unaffiliated," the arcobaleno informed him matter-of-factly. "Might as well take this chance to recruit him into your family, Dame-Tsuna."

"No, no, no, no, no, Reborn!" protested Tsuna, pushing his chair back with a scrape and remembering to pitch his voice lower this time. "I told you, I'm not going to become a mafia boss! And I don't need a hitman doctor to swear his loyalty to me!"

"Oh, but it sounds like it would be such fun," interjected Shamal, his professionalism falling away to be replaced by a teasing smirk.

"You don't encourage him!" Tsuna turned to yell at him, completely forgetting about his own hesitance from moments before.

"Look Dame-Tsuna, he's already agreed," Reborn told his student, a satisfied smirk pulling at his features.

"I SAID I DON'T WANT A HITMAN!" Tsuna yelled.

"Oh, but you already have one," Shamal pointed out. "I don't see what's so bad about one more."

"What?" demanded Tsuna.

"Congratulations on your second family member, Tsunayoshi!" Reborn said, his voice entirely too amused.

"Second?" asked Tsuna, turning to him. "Who's the first?"

"I am, of course."
