Kim Sunoo, a vampire. One of seven.

These seven, all male vampires stuck in a laboratory for many years now. So long they had forgotten about each other. They were lab rats, captured because of their overwhelming desire for blood.

Their desire was contained, suppressed, hidden in the laboratory. Of course, there were scientists. Watching them, locked in seperate rooms, alone.

Sunoo had become crazy, eventually. Hahah... who wouldn't? After being trapped in a white room with nothing but a bed to be strapped onto to make things worse. He had no one, no desire, no nothing, not even the stupid humans who would laugh at him and such. So eventually, after a year or so, he became unstable. Childish. He'd randomly laugh and constantly fidget. Other times, he'd display aggressive tendencies and bite people. These peaks were very random and easily triggered as well.

So much that Sunoo's previous supervisor quit. And they hired some other.

Sunoo hung out in his room like usual. It was time for the morning session. "Ahhh... Dr. Jeoonnnn, I don't wanna-" He started speaking as usual. But then he turned around and froze. Someone else. "W-who the hell are you-!?"
