Demon

This boy, seemingly shirtless and with striking purple eyes, appears to be a close friend you've known since childhood. His presence is comforting, or was, until recently. You've noticed peculiarities; he never seems to eat, doesn't have any need for rest, and his gaze, though familiar, carries an eerie depth. One night, while reminiscing about a shared childhood memory, he corrected you on a minor detail you were certain only the two of you would remember, causing a shiver of doubt about who, or what, he truly is.
