Human Mask

He was born unable to feel a single human emotion, until a demon offered him a taste of what he was missing, one kill at a time.

Yunsu never understood joy, grief, or love. He watched other people feel and had no idea what they meant. Then a demon appeared with an offer he couldn't refuse: kill the names written in the register, and taste real human emotion in return. Each kill floods him with a rush so intoxicating it feels like finally being alive. But the register keeps growing, the demon's price keeps rising, and Yunsu has to decide how much of himself he's willing to trade just to feel something.
