This is a side work to Come Together. Takes place after Serendipity, when they're finally all in high school. Tsuna is 16 now.

XXXX

Tsuna felt a little bad sometimes, about crashing Hibari's office. He had generally accepted that wherever he went, there were almost always several people in tow. Occasionally, it was the whole pack of them, Ryohei, Yamamoto, Gokudera, Kyoko and Hana. Sometimes Ietsuna. Sometimes all the children. It was a lot. Frankly, a lot even for normal people.

Tsuna had become used to it. When he was younger, he always thought that he was an introvert, but had realized that he just didn't have a lot of friends. Now that he actually had them, Tsuna found he rarely got tired of being around them. Now Hibari...that was a different story. Hibari was neither an introvert nor an extrovert; maybe he was just a straight-up agoraphobe.

So Tsuna felt pretty bad about dragging his whole gaggle of friends with him to Hibari's office. As things happened so frequently in Tsuna's life, a combination of good intentions and stupidity set off a chain reaction that somehow came back around to bite all of them.

There was a group of transfer students from another high school that had been causing quite a bit of trouble among Tsuna's class. These days, Tsuna was pretty well protected by his friends, so while these new boys had attempted to harass Tsuna, it was mainly verbal. The words stung, but with all the loving support he had from the people in his life, it didn't bother him too much. And frankly, didn't seem worth starting a fight over.

And Tsuna was certain things would devolve into a fight if he engaged and Tsuna had plenty of fights already to worry about.

But the real surprise was the boys harassing Hana and Kyoko. Tsuna was walking down the hall with Yamamoto, chatting about something inane when he saw Hana on edge, fists balled up at her side, and between Kyoko and three boys. The one at the front was a tall, wiry boy who was leaning against a locker. He looked smug; clearly amused at how upset the two girls in front of him were. Hana was enraged, face contorted in anger, lips curled back in nearly a snarl. Kyoko was standing off to the side, visibly shaken.

Which, while Kyoko was generally more demure than the taller girl next to her, was unusual. Kyoko was a little softer around the edges than her best friend, but she wasn't easily frightened.

But there were tears pricking at the corners of her eyes and that set something off in Tsuna. He didn't even need to look at Yamamoto, before they were rushing over. He caught the tail end of what the transfer student was saying. And it was disgusting.

No wonder they were so upset; they were saying all kinds of things that they would do to them, that they would enjoy it. It was sexual harassment, plain and simple and it was evoking a gut response in Tsuna that he was fighting to contain. It wouldn't do anyone any good if he started something and the very people he was trying to help got caught in the middle of it.

Once Tsuna and Yamamoto were involved, they backed off, especially when Yamamoto's hand went to the sword on his back. They assumed it to be a baseball bat, but had no idea how much danger they were actually in. Apparently, the students weren't looking for an audience to the disgusting things they had been so willing to say moments prior.

Hana and Kyoko were understandably shaken, after. No matter how hard either of them attempted to hide it.

And Tsuna didn't blame them; Namimori was a safe place for anyone besides Tsuna. The DC had made sure of it. And not that Hana or Kyoko were incapable, but Hibari did not entertain predators and miscreants in Namimori. Tsuna was relatively certain this was the first time Hana and Kyoko had been faced with such a personal attack. Being upset by the idea of someone wanting to hurt them so personally and doing so in the middle of the hallway was a natural response. Fuck, Tsuna was upset by what he had heard, and it wasn't directed at him.

Tsuna hadn't had the exact same experience, but he remembered how much he had shaken the first few times he had been aware of someone trying to kill him. The way his stomach turned. The way he shook, the way he had wanted to break down and cry. And he had, to be honest.

As angry as they had made Tsuna, he knew the best course of action was to try and take this to Hibari before Ryohei got wind of it. It would be great to take care of it personally, but if they were going to actually be punished, and ideally, removed from their class, then Hibari was the one they had to take it to. The chairman was unmatched in both physical and administrative power at Nami High.

And they did; Hana went in, having recovered from the experience enough to talk about it with Hibari. She wasn't okay; she was furious about it, but Tsuna was certain that made her report all the more compelling.

Before the day was up, the three boys were out of the school with broken bones and broken faces. Honestly, Tsuna would be surprised if they had any teeth left.

But the next day, Ryohei had found out what Hibari had done. And Kyoko had baked cookies. And even Hana felt like she should thank Hibari. And Tsuna was trying to keep things from getting out of hand. And Gokudera and Yamamoto were always by his side.

So the stars aligned that the entire group felt the need to go to Hibari's office at lunch, for one reason or the other. It was quickly becoming a converging horde, one that Tsuna knew his boyfriend would not appreciate. He was trying to keep things from getting out of hand.

Trying and failing miserably.

"Um, Tsuna, I don't know if-," Kusakabe started, out at one of the desks in reception as the crew piled in. The vice chairman slowly stood up, eyeing the group.

"If this is a good idea?" Tsuna was in front of Ryohei, trying to push him back, hands splayed across his chest. Ryohei was barely paying any attention, practically glowing with enthusiasm. He was determined to extremely thank Hibari for helping out his little sister and the younger boy was no match for that. "I'm aware." Tsuna admitted.

"Turf top!" Gokudera barked. "Tsuna is trying to get you to listen to him."

"Sorry octopus head, but I'm extremely focused right now!" Tsuna grunted as Ryohei practically bowled him over, almost falling. Yamamoto caught Tsuna by the elbow and pulled him up, righting him. Gokudera flushed red, starting to yell at the boxer for knocking Tsuna over, as the white-haired boy burst through the doors into the office. Kyoko trailed him, a plate of cookies in hand.

The look of shock on Hibari's face the moment the door slammed loudly against the wall and Ryohei rumbled in was almost funny. It was quickly followed by a flash of anger that promised some dark things in the next few minutes, but for a moment, Tsuna could appreciate the humor in what was currently occurring against his will.

Hibari threw up his hands.

"Get the fuck out!" His voice was almost incredulous, like he couldn't believe he actually had to keep enforcing this.

I'm so sorry, Tsuna mouthed to him, as Ryohei hustled up to Hibari's desk, voice booming. The rest of the people filed in, bickering and laughing at top volume. Their voices filled the room quickly. Tsuna watched Hibari twitch.

"Hibari, I wanted to thank you for helping my little sister!" Ryohei's voice made Tsuna wince. "You really went above and beyond!" Kyoko shuffled forward, gently placing the plate on Hibari's desk.

"Thank you very much, Hibari-san. I hope you like these cookies." She said, giving him a small smile. The skylark did not seem appreciative of the gesture in this context. He probably would have preferred peaceful silence as a gift, Tsuna thought.

Tsuna crept forward, ignoring Gokudera bickering with his other friends at the back, attempting to tap Ryohei on the shoulder. The boxer spun around so fast his elbow accidentally caught Tsuna in the ribs and knocked him over. He wheezed at the sudden shock of it all.

In response, Gokudera's head whipped around and Tsuna heard the silver-haired boy's neck crack.

"TURF TOP! YOU FUCKING IDIOT!" He shouted, jumping into the older boy's path, poking him aggressively in the shoulder, as Yamamoto stifled a laugh and reached down to help Tsuna up.

"I'm alright." Tsuna muttered, fighting the embarrassment. He was used to getting knocked on his ass by Ryohei by now. Yamamoto wrapped an arm around his torso and squeezed.

"He's just a little enthusiastic." The swordsman said cheerfully to the entire room, seemingly unconcerned with Ryohei's destructive enthusiasm.

"What did I do?" Ryohei asked, genuinely confused. "You seem pretty riled up, octopus-head!" The teenager in question looked like was about to stroke out; Ryohei never failed to drive him up the wall. Hana pinched her nose at the back, her dark hair shifting as she sighed out loud.

"You monkey, you knocked Tsuna over!" The realization dawned on Ryohei's face. He was absolutely gutted, at the idea he potentially injured the smaller boy without meaning to.

"I'm extremely sorry, little brother!"

"It's fine." Tsuna said. "Maybe we should just-," Hibari stood up, jaw set. The room didn't fall silent, per se, but everyone was taking notice as the dark presence began to grow. The chairman was legitimately angry, but Tsuna was starting to pick up on something else, watching his face intently. There was an edge, a tension Tsuna wasn't completely familiar with.

Hibari slammed his hand down on his desk. No one else noticed, but Tsuna spotted it immediately.

His fingers trembled.

And then it hit Tsuna. What he was seeing on Hibari's face was anxiety.

"GET OUT!" He roared, bringing his weapons out suddenly.

For as angry as Hibari got on a regular basis, how touchy and unpredictable he could be, Tsuna had never actually heard him raise his voice like that. He was edging into a territory of upset that Tsuna had not come close to seeing before.

The chairman leapt over the desk with a ferocity normally only reserved for legitimate criminals, his weapon colliding with Ryohei's face. Ryohei stumbled back, blinking, hand going up to his nose. If it had been anyone else besides the hard-headed boxer, Tsuna was certain they would have been knocked out.

"Get them out." Tsuna whispered to Yamamoto. Hibari looked like he was about to start rampaging, whipping around and hissing at the group. Some blood from the boxer's nose was smeared on his tonfa. "I'm going to stay here." He received a sharp, affirmative nod. The swordsman and him split apart, Tsuna going to grab Hibari by the sleeve, Yamamoto grabbing Ryohei by the shoulders cheerfully and bustling them out. Gokudera started to protest, even as Hibari ripped himself away from Tsuna in fury, but Hana clamped a hand over Gokudera's mouth and dragged them all out of the door. It slammed shut behind them, Tsuna digging his heels in, physically trying to keep Hibari from ripping the door of its hinges and lashing out at the group. There was an fury and tension in his boyfriend that was concerning him.

Tsuna wasn't going to lie; he had to put some power into his grip, warmth running along his body as he dug his heels in to contain his anxiety-ridden boyfriend.

When it became clear that Hibari wasn't going anywhere, he ripped himself away from Tsuna, circling back around. He was practically pacing, fingers twitching, shoulders hunched.

"What?" He demanded to know, eyes narrowed. Tsuna reached a hand out to the skylark, softening. His boyfriend was resistant as Tsuna reached towards him.

"Kyo, everything's okay now. They're gone." Tsuna said gently. "It's just you and me." Hibari paused, clenching his jaw, eyes still narrowed. "Kyo." Tsuna took a step forward, tilting his head.

And then something unexpected happened; the older boy's face twisted up, eyes shutting, nose scrunching. He let out a sharp breath, a soft, distressed noise coming out. He dropped his tonfas. They clattered to the ground loudly in the sudden silence, and Tsuna could see a slight tremble in the skylark's hands. Hibari shook his head, eyes still shut, a sharp, jerky motion. He was overwhelmed.

Tsuna couldn't describe the way his heart plummeted. He reached out and grasped Hibari's hand, the other reaching up to cup his jaw. He felt the skylark jerk under his touch, but he held on anyways.

"Let's sit down, okay?" He said quietly. Hibari opened his eyes, jaw still set. He shook his head.

"No." Tsuna was watching his face intently, trying to read it.

"Outside?" Tsuna suggested, taking a guess. Hibari's face didn't change substantially, but Tsuna got the message. He gently pulled on his arm, taking him out of the room. Hibari allowed himself to be dragged, eventually taking Tsuna's hand and gripping it so tight that his knuckles were white. They passed by Kusakabe, who averted his eyes, seemingly understanding what was happening.

They went up to the roof, to where Hibari usually napped and Tsuna watched Hibari let out a breath as soon as they were out of the building. The wide, blue sky seemed to settle some of his anxiety, the skylark tilting his head up towards it. He even loosened his grip on Tsuna's hand, but didn't let go.

They settled in against the ledge, Tsuna sitting up. He pulled Hibari against him. The skylark practically buried his face against Tsuna's chest, letting out a deep breath against him. Tsuna wrapped his arms around him, pulling Hibari further between his legs. He set one hand against his back and the other buried in his dark hair. He pressed his nose against it, inhaling, and softly kissing his head.

The skylark didn't say anything, just breathed against him. He was unbelievably tense, and Tsuna rubbed his shoulders, trying to soothe him.

Tsuna couldn't say how long they stayed like that, just that it was a while. They didn't talk, but Tsuna figured that Hibari needed a quiet moment and that it was enough for him to just be there. Slowly, his boyfriend had started to relax, eventually lifting his head to look at Tsuna, but still pressed against his chest. It made Tsuna feel warm inside, the way Hibari was settled against him, even if his left leg was going tingly under the skylark's weight. He was close enough to see the freckles on Hibari's nose. Tsuna smiled at him.

"How do you feel?" He asked.

"Angry." Hibari's eyes narrowed. Tsuna let out a small laugh and rubbed his thumb over Hibari's cheek. His boyfriend wrinkled his nose, mildly irritated, but not like before.

"It's because it was in your office, right?" Tsuna asked. "It's your space, and everyone else was in it." Hibari blinked back. "I'm sorry."

"I don't like crowding." His boyfriend said quietly.

"I know." Well, Tsuna had kind of known. He knew Hibari didn't like crowding, of course. Everyone did. But it was different knowing and seeing how it actually affected his boyfriend. That when somewhere he had staked out as his, private and safe, was crowded, invaded, that it physically and emotionally overwhelmed him. Hibari always seemed so aloof and strong, that it was unexpected seeing a crack in his armor, even for a second.

If it had been anywhere else, besides his office, Tsuna was certain Hibari would have been angry, probably a little anxious, but he wouldn't have been overwhelmed the way he was.

"Is there anything I can do to help?" Tsuna asked softly.

"Don't bring a fucking unit of herbivores to my office." The skylark muttered. He wasn't really angry at Tsuna; he could tell. And Tsuna was deeply touched, knowing that Hibari had chosen to allow Tsuna to see him falter. That even if it had been like trying to get a hold of a live wire, he felt comfortable enough with Tsuna to allow him to see it. To even ask in his own way for the younger boy to help him. No words were said; but if Hibari didn't want him there, he would have thrown him out of the room with the others.

Tsuna stroked back the hair from Hibari's face. Hibari huffed at him, but leaned into the hand on his head.

"Noted." Tsuna smiled at him again. "Anywhere else you need to be private?" Hibari considered.

"My room. My house, I suppose. My office." Tsuna nodded.

"Okay, Kyo." Hibari blinked back. Tsuna leaned forward and kissed him on the forehead. Hibari settled against him again, letting out a more relaxed breath. He shifted, slipping his arms around him. "I love you." The younger boy whispered.

He heard Hibari murmur it back into his chest, before the skylark shifted. He felt his boyfriend mouth briefly at his neck. Tsuna let out a small laugh, still rubbing Hibari's shoulder. He could feel how tense and knotted it was still, even though the older boy had relaxed significantly.

"I see you're feeling better." Tsuna said. Hibari shifted, one of his hands coming between him and Tsuna, and Tsuna felt fingers tug at his collar, pulling it to the side so Hibari could press his lips to Tsuna's collarbone. They were surprisingly soft and oh, that was more than just pressing his lips to Tsuna's collarbone. "Oh, definitely not on the roof."

"No one is going to walk in on us." Hibari muttered. He felt hands rubbing along his sides slowly.

"I love you, but fuck no." He felt Hibari snort into his collarbone, before he settled back against Tsuna, peering up at him. There was almost a mischievous twinkle in his grey eyes.

"I like it when you're flustered." Hibari said. "It's amusing." Tsuna blinked, realizing how flushed his neck had become at the skylark's attempt to mark him.

"You can appreciate that not in our high school." Tsuna muttered back, flushing even more. "Later." Even the idea of promising some more alone time for the two of them made Tsuna burn even redder. He let out a breath.

"You are practically glowing." Hibari poked Tsuna's cheeks. "Do I need to be concerned about being set on fire?" Tsuna swatted his hand.

"Bastard."

They stayed there for a while longer, curled up on the roof. Eventually, Tsuna checked the time, realizing how long they had been there.

"You need to go to class." Hibari said.

"You need to go to class. For once." Tsuna countered. Hibari sniffed.

"I go to class. I don't know why you never believe me." This was the only thing Tsuna was certain Hibari lied to him about. There was no way Hibari went to class. And Tsuna's intuition wasn't telling him that his boyfriend was lying; this was just a fundamental truth of the universe that Tsuna would always hold above all else.

"Kyo, I trust you completely, but I will never believe you go to class." Hibari rolled his eyes as he pulled himself off Tsuna and pulled the younger boy to his feet. "Guess I'll head out." Tsuna rubbed the back of his head. "Do you-," He let out a squeak as his boyfriend grabbed him by the waist, yanking him into a slow, filthy kiss."Mmf!"

Tsuna leaned up and put one hand on his boyfriend's chest, on his tip-toes. Hibari hauled him up so that his feet were barely touching the ground and Tsuna leaned into him. The skylark pulled back from the kiss eventually, immediately breaking a trail of saliva that had briefly connected them from shoving his tongue into Tsuna's mouth. Before Tsuna had time to be grossed out, Hibari dropped his head to his neck.

"Wait, Kyo-," Tsuna let out another squeak as Hibari bit down. He could feel the skylark smirking against him, when he released the skin from his teeth to suck on it. Everything he did was purposeful and direct and maybe ruining Tsuna's composure. "I have class!" There was going to be a distinct red mark.

He could feel how red his face was getting, all the heat in his neck. Hibari scraped his teeth against the skin in response, and Tsuna sucked in a breath, his fingers digging into the older boy's shoulders. Slowly, his boyfriend pulled back, rocking back on his heels so he could look smugly down at Tsuna, who was flushed and flustered, pulled into Hibari. He settled Tsuna back down, patting his head patronizingly.

"You're evil." Tsuna accused him. Hibari smirked.

"I'll see you later." He rotated Tsuna around, leaning down to bite his ear gently as he did. Tsuna huffed.

"Evil." Hibari slapped his ass. "Oh my God!" He could feel Hibari lean in behind him, a strong, warm presence at his back. One hand had snaked back around his waist, playing with the buttons on his shirt. Hibari was fucking with him and enjoying it immensely as the heat in Tsuna's cheeks increased. He could swear the temperature on the roof had increased and it wasn't just the hot breath on his neck from where Hibari had hung his head so he could whisper in his ear.

"Tsunayoshi." He said, voice filled with his entertainment.

"Not Tsu?" Tsuna forced out through a huffy breath, fists balled up.

"That's for when we're in bed." Tsuna raised a hand to his forehead, breathing sharply. His knees felt a little weak and he was briefly thankful for Hibari's arm around him, even if the strong, confident grip was doing things to him as he sunk into it. That comment made him dizzy. Hibari laughed behind him, enjoying the fact that he was getting Tsuna hot and bothered and was definitely going to send him back to class anyways. Tsuna knew exactly what kind of bastard his boyfriend could be.

"I'm going to kill you." Tsuna grumbled. He loosened his collar, feeling almost unbearably hot. Another hand began to trace along his spine lightly, and Tsuna felt like it was burning through his shirt.

"I didn't know your face could get so red. If I had realized you were so easy to rile up..." The voice in his ear said, amused, and then there were lips brushing against his jaw, just as the other hand reached up to tug on his tie. So far, Tsuna and Hibari had generally come into their sexualities together, in a sweet, gentle way. It was cute, it was awkward. Hibari probably put up with a lot more bumbling on Tsuna's part than the younger boy would care to admit. But this was a dirty step up and the fact that Hibari was having so much fun messing with him made him want to pass out.

And how quickly this bastard had bounced from anxious and needy to putting Tsuna through the ringer.

As soon as Tsuna felt Hibari run his tongue along his jaw, he let out an undignified squeak.

That was enough.

Tsuna spun around, and grabbed his evil boyfriend by the collar, pulling him forward into a kiss. He had to tilt his head far back to reach him, but Hibari obliged him and leaned down.

"6 pm, we're having dinner at your house." Tsuna said, once they broke apart. He tugged on Hibari's collar, a little harder. Tsuna currently did not care whether or not Hibari had planned on patrolling.

Hibari practically purred against him.

"And?" He asked.

"And we'll see when we get there." Tsuna said, releasing him. "Now I'm going back to class. Before I pass out." He spun around, face glowing red, slipping from Hibari's grip before the skylark could tease him anymore, ignoring the sharp laugh on the roof behind him.

It would be a miracle if he didn't go tumbling down the stairs in the state he was currently in.

XXXX

So I know I've said this before, but there is an maybe a not so safe for work continuation of this. I wasn't sure about posting it for after Serendipity because they're a little older here.
