Roach

In the dead of night, you shed your skin, a husk of a thing, leaving you sticky, renewed... and repulsive. Everyone that lays eyes on you lunges towards you, their eyes full of disgust and intent to kill. You need to run. Nearly overnight, Taesu Im goes from a terminally ill family man to the most reviled existence on Earth. But it's not just people's perception of him that's changed... it's him. Something has turned him into a half-man, half-cockroach, and he needs to find out what—or who—did this to him before he gets squashed.
