Hidan wasn't jealous. He was anything but jealous. That feeling didn't exist in his dictionary, and no one ever stirred such an unfamiliar feeling within him. Anger? Plenty of times. Jealousy? N-E-V-E-R. Never. He swore to Jashin that he wasn't, and now he had to sacrifice more of his blood because he lied.

You know what?

He was not going to offer more of his blood. He was going to offer more of that bloody blonde's blood. After all, it was all because of that bitch that he was experiencing this alien feeling. He really wanted to murder.

"Why do you look as if you want to murder someone?"

"Because I fucking do," Hidan snapped at Kakuzu and glared at him, making it really clear that he didn't want to be near anyone right now. Kakuzu has no in-built sense of danger though (it was long gone; he definitely spends too much time with Sasori) and took a seat beside Hidan.

"So why do you want to kill someone?" Kakuzu asked. Hidan continued glaring at the older man but he relented after realising that it wasn't going to work, nor was Kakuzu going to go away. And he would move but he found the place first damn it.

"I want to fucking kill that bitch Deidara," Hidan confessed before deciding to add, "and Sasori."

"Are you jealous?"

Hidan took the nearest rock and flung it at Kakuzu. The older man barely managed to throw an arm in front of his eyes to protect it. He stared disdainfully at the cut in his arm. If anybody else had thrown that rock, it would have been just a simple scratch which did not require any medical attention, but Hidan was the one who had thrown the rock, so the damage definitely needed some sort of medication. Damn. He didn't want to spend money on this.

… Maybe he'll get Sasori to steal supplies for him.

Also, if it had been anyone else who had thrown the rock, the other person would be immobilised and admiring the inside of an ambulance right now. Kakuzu was still trying to figure out why he wasn't even the slightest bit angry at Hidan. He felt nothing more than anything.

Crap. He was getting used to being abused.

Note to self: definitely spending too much time with Sasori.

… which means that asshole owes me those medical supplies…

"Does it hurt that fucking much, you pussy?" Hidan asked in annoyance. Kakuzu snapped out of his thoughts and wrenched his eyes away from the wound to look at the younger student.

"No."

Then he remembered what they were talking about.

"Do you like Deidara or something?"

Hidan spent the next ten minutes trying not to throw up and tossing every single curse word available in the world at Kakuzu. Then he spent the next twenty minutes doing it in different languages. Kakuzu never knew that there were so many languages in the world. And he was an atheist, but he felt the need to pray to some god after Hidan was done.

"Okay, you don't," Kakuzu concluded. It was the safest thing to say. He didn't want to be subjected to another round of verbal abuse.

But that didn't mean that he wasn't still curious.

"So why?"

Hidan glared at him but said nothing. It wasn't like he didn't want to tell Kakuzu; he would be more than happy to vent his feelings, because Hidan wasn't the type of person to keep his feelings to himself. He was a volcano. A very active one. A slight trigger would make him spew lava in all directions and destroy everything unfortunate enough to be in its way.

It was just that he never felt jealousy before, because he never felt the need to, never cared enough about anyone to feel jealous.

He hated that Deidara was spending so much time with Sasori. Sure, they were both medical students so that meant that they already had more in common than anyone else and they were both geniuses which also meant that it was more often than not difficult to understand what they were talking about. Hidan was no genius. Heck, he wasn't even smart. He actually did work hard to enrol into Tokyo University.

But that wasn't the point. He could deal with it if they were only talking about studies. Honestly, he wouldn't even care if they went to each other's houses every day to talk about medicine. No offense to them, but he hated science. All of it. But it was apparent enough to everyone that they weren't just talking about medicine.

They were talking about art.

Seriously. Hidan didn't even know that Deidara liked art, let alone know that the blonde had enough skill and knowledge about the damn thing to have an intellectual and sound argument with the redhead. He was Deidara's best friend damn it. He was supposed to know all the blonde's likes and dislikes. Now he didn't even know that Deidara practically loved art. But Sasori knew.

Talking about Sasori, it appeared that his friends didn't know that he had that particular interest either. Maybe he wasn't the only one who was upset.

"Why the fuck not?"

"You're jealous because he's all chummy with Sasori suddenly?" Kakuzu tried slowly, hoping that Hidan didn't erupt.

It took a while, but he eventually got a response.

"Deidara's my best friend."

"And you're the king of the world, un."

Sasori glared at Deidara. He liked the kid really, despite everything and all their misunderstandings and crap. They were similar and they both loved art. To Sasori, that was reason enough to like someone. But seriously, of everything, he never expected art to be the centre of their conflict.

"It is illogical and unsound to think that art is fleeting," Sasori replied, rolling his eyes.

They were in the cafeteria waiting for the rest of the group to arrive. It was lunch time and lecture ended early for Sasori while Deidara's tutorial was cancelled.

"Now you're implying that I'm mentally unfit and should be sent to an asylum, un?" Deidara shot back.

"You inferred that yourself," Sasori retorted, feeling his patience running thin. Again. It had been that way for weeks now.

They would meet, strike up a nice conversation, drift to art and start arguing. Sasori wanted to talk and appreciate art, not have a fight about it.

"How can art be eternal?" Deidara snapped, glaring at Sasori. "Humans aren't even eternal, un. And the ones who think they are, are in the aforementioned happy house."

"Humans aren't art."

"And nature?"

Sasori glared.

"I'm talking about mad-made art, Brat."

"Since when was art limited to 'man-made', Danna, un?"

"Are you guys still going on about it?" Konan asked in amusement.

"Yes," they both replied curtly.

Konan thought it was kind of cute that they had these kind of arguments (art terminology aside), but more than anything, she was seriously happy for them. In all the time she had known Sasori, she had never seen him so passionate about something. It made him seem more human.

"Well, fuck," Hidan scoffed and dropped into the seat beside Deidara.

"Afternoon to you too, un. How was lecture?"

"Boring shit."

The rest of their group eventually arrived and Sasori and Deidara engaged in yet another heated argument. The others watched on in amusement. Ever since the two started these quarrels, it had become a source of entertainment for the others. Not for Hidan though. Without saying anything, he left quietly.

As soon as he was out of the cafeteria, Deidara halted the conversation.

"Sorry, Danna, but this is more important, un."

Sasori nodded and took a sip from his coffee. He didn't mind not arguing. Heck, he didn't even want to argue. Art is eternal. Fact. Art is fleeting. Crap. Period.

Deidara turned to Kakuzu.

"What's up with my best friend, un?"

Kakuzu stared at Deidara in shock. He was annoyed at the blonde previously because Deidara hadn't seemed to pick up on the fact that Hidan was upset. In fact, he had been planning to tell Hidan to ditch Deidara and find himself a new best friend. When Hidan left, Kakuzu was this close to punching Deidara. He definitely didn't expect this.

"Oh come on," Deidara said, rolling his in exasperation. "Did you think that I wouldn't realise that something's wrong with Hidan, un?"

"Then why don't you ask him yourself?" Kakuzu shot back.

"He wouldn't tell, un," Deidara said and sighed. "He's a selective volcano, and now he's a dormant volcano to me, because obviously I did something, un. So what did I do, un?"

"Shouldn't you know?" Kakuzu asked, raising an eyebrow. Honestly, he wouldn't know either if he were in the blonde's position but he thought that a best friend should, but he supposed that the two hadn't really known each other for a long enough time.

"I don't, un. So tell me, un," Deidara snapped. He felt guilty as hell for upsetting Hidan already. He wanted to rectify. Now.

"He's jealous that you're best friends with Sasori now."

"Stupid, un," Deidara said simply and stood up.

"You still have lecture," Konan reminded him.

"Screw lecture, un. Hidan's more important than that, un."

Hidan's punching bag lay in ruins on the floor. Now he had to get a new one. Damn.

"You're certainly angry."

Hidan felt his hair stand on its ends as he jumped and turned around, glaring accusingly at the offender.

"Fuck, blondie, don't freaking scare people like that," Hidan shouted in annoyance.

"I think you're being angry at the wrong thing, un," Deidara said simply as he made himself comfortable on Hidan's couch. "Do you remember answering the door?"

Hidan stared at his completely sealed door and stared at the blonde.

"You bitch. You fucking broke into my house," Hidan said in irritation, but he couldn't keep the hint of amusement out of his voice.

"Yeah, un."

"Fucking why?" Hidan might be slightly less annoyed now, but that didn't mean that he was going to forgive the blonde for anything. He didn't care that Deidara probably didn't do anything wrong.

"To give you this, un," Deidara said casually, fishing out a small bottle. Hidan couldn't really see what it was so he went over to take a look. Deidara passed the container and he stared at it. It contained a red liquid. About 700 millilitres.

Blood.

"What the fuck blondie?" Hidan asked, raising the bottle questioningly.

"My blood, you douche, un," Deidara said.

"700 millilitres is way too fucking much, you blithering idiot," Hidan scolded but even he couldn't keep the hint of concern out of his voice. Now that he looked at the blonde properly, he realised that the blonde was looking paler than usual, but the usual smirk was still on his face. It gave Hidan some comfort at least.

"No fucking one would help you bloody draw that much fucking blood," Hidan pointed out.

Deidara stared at Hidan like he was stupid.

"I'm a medical student, un."

Hidan felt like throwing the punching bag at him.

"Why do I need your fucking blood anyway?" Hidan snapped.

"You need to sacrifice my blood to your Jashin, un."

"In Jashin's name, why the fuck?"

"Because I'm your best friend, you bitch, un. For life."

"Deidara, I have good news for you!"

"Yes, Akasuna-sensei, un?" Deidara asked, raising an eyebrow as the old lady made her way towards their group's table.

"Hello Sasori," she said, smiling proudly at her grandson who nodded in return. She then turned to Deidara.

"You're joining Sasori for his internship."

Joy.
