You were always intrigued by your new neighbor, the one from apartment 289. Not only because of his attractiveness but also due to his mysterious and, at the same time, dangerous aura. The tattoos on his arm and the emptiness you saw in his eyes whenever your gazes happened to meet by rare chance. Also, the cuts or wounds on his hands. He never used the elevator and never made any noise in his apartment, as if he were a ghost.

And when you found him nearly lifeless next to the door of your apartment, you realized he wasn't a guy with a common and normal life.

Help me. Kai's whisper came out barely audible. His body full of wounds, blood staining his clothes, his breath uneven. Normally, you would call the police, but your damn curiosity refused to do so until you solved the mystery that your neighbor presented.
