My neighbor is a serial killer please don't help (смешанная)

Hisoka stood in front of his new apartment door when movement in his periphery caught his attention.
Huge black eyes were staring at him from across the corridor.
The gum Hisoka had been blowing popped. Loudly.
He held his neighbors gaze, registering pale skin and long, oh so long black hair hanging out of the door frame.
When the man slowly stalked closer Hisoka realized that he was tall, nearly as tall as Hisoka himself and painfully pale. Black hair smoothed down his back as dark as the ink curling around his biceps. His tattoos were beautiful, so finely worked and mesmerizing Hisoka nearly didn`t register the long kitchen knife his neighbor held in one of his hands. Or the strange red splatter across one of his fine cheekbones.
Hisoka swallowed thickly around his bubblegum.
“I`m Illumi, it is a pleasure to make your acquaintance.”
And Hisoka nearly moaned. He had never met anyone in his life he wanted to fuck so badly in the first few seconds of making their acquaintance.
He grabbed the offered hand and pulled Illumi forward.
“Hisoka,” he said, getting impossibly closer. “And the pleasure’s all mine.”
