I had sworn to myself I would never start posting a fic before I was finished typing it down. I had. But good resolutions never last, so here you go.

Disclaimer: If the likes of me could own Naruto, we'd be several thousand people trying to rip each other off to gain that right. So no, it still isn't mine. Sigh...

Warning: If the slightest sight of blood makes you go all faint, than this fiction isn't for you. I'm not a psychopath -okay, I am a psychopath, though not when I write- but this is a vampirefic, people. There's a real need here.

Oh, and this fic will contain yaoi.

Enjoy.

"Nunquam lamiae morde me dice. - Never say 'Bite me' to a vampire."

"Symbiosis; from the geek syn, meaning 'together', and biosis, life. The living together of unlike organisms. Or so is the definition given to you by Heinrich Anton de Bary, German mycologist, in 1879. Who can give me example of symbiotic species?"

Several hands rose into the air, but some students didn't bother.

"Clown fish and anemones!" Inuzuka Kiba was as loud as always. I looked away, vaguely hoping the noise he made would vanish with his face. Biology class had barely started, and I braced myself for the long hour I would endure with the loudmouth, cursing the administration for putting me with such mind-abusing fools.

Next to me, Hyuuga Neji sighed, echoing my thoughts. "Too bad the course is worth it," he told me in an inaudible murmur. "What a pain. I don't see what Hinata sees in him."

I had been asking myself the same question. Hinata was Neji's timid sister, and her shyness was such that I had never managed to hear her articulate a single sentence without stuttering. And yet, despite her timidity, she seemed to appreciate Kiba.

"Alright, the clownfish. Now that's what you call mutualism; both species derive a benefit. You also have commensalism, where only one of the two individuals will gain something, without harming its 'host'. And parasitism." He did not need to explain the last part.

Neji elbowed me, a slight smile on his lips as he took notes. "I'm guessing your case is the third one," he suggested quietly.

I shrugged, ignoring the remark. Arguing with a member of the Hyuuga clan was pointless; they'd smile and agree while affirming the opposite opinion once you were finished. And I was not in a good enough mood to stand this behavior.

"You're visiting him today, right?"

I nodded wordlessly. Neji sighed, knowing how much I disliked talking in public, and the reason for it. Should my lips part, I would inevitably become the subject to pointless conversations with any girl in a ten-meter radius. And somehow said conversations would stretch until the bell rang. My head pounded just to think about it.

The Hyuuga noticed me rubbing my temple. "With enough luck you'll be fit tomorrow," he said. "That headache of yours will be gone."

Looking at my notes I sighed, wishing he were right. The pain had been constant since the beginning of term. I waited until the end of class to answer. Once we were safely hidden away from female view, I finally opened my mouth.

"Dr. Hatake told me not to bet on it. Apparently the guy's stubborn."

"I don't see how different it can be," Neji replied with a shrug. "Good luck though."

I nodded, and headed towards the end of the hall. The University of Konoha was known for the fact that it was linked to one of the most prestigious hospital of the country; here were treated the most serious cases of diseases; the study of bacteria, the innovations of new medical serums and techniques were linked to this place, and college students benefited directly from it.

The wall switched from sky blue to the traditional white proper to any hospital, and students brutally vanished, replaced by doctors and interns, then patients, as I walked further on. My destination was located at the far end of the building, where Dr. Hatake, whom I had never met, waited.

I felt my pulse accelerate, and I forced myself to ease my breathing. But as I kept advancing, I soon realized that it was pointless. Stopping dead in my tracks, I inhaled deeply, and steadied my nerve-wrecked body. I despised this lack of control. Instincts dictated by memory alone demanded that I turn heels. But another part of me required me to continue. It was only once I had my body completely under control that I walked down the hall.

You could say my apprehension was normal. That my basic human instincts were surfacing in order to keep me away from danger my brain had refused to register. Somehow I wondered if I wasn't just mad. Or too curious for my own good.

I, Uchiha Sasuke, was about to meet a vampire.

FOR THE TWILIGHT HATERS: I couldn't resist, forgive me. Hopefully I've dealt with the cringe-worthy part of Stephenie Meyer's novel. I'm too lazy to explain what I'm talking about or how I fixed it, so if you're really curious, check my profile. Or keep reading, your choice.

I won't mind reviews at all, anytime, from anywhere.
