The Unknown Survivor group (Y/N Riddle x Rick Grimes)

No one knows where Y/N Riddle came from only that they are a ghost in the apocalypse. Cold, calculating, and deadly, Y/N moves like a shadow, leaving behind nothing but fallen enemies and whispers of fear. With a past as scarred as their body, Y/N has long since abandoned the idea of attachments. Survival is all that matters. But when Y/N crosses paths with Rick Grimes and his group, something begins to shift. Rick sees beyond the hardened exterior, beyond the emotionless mask, and into the person beneath. As tensions rise, battles are fought, and losses cut deep, Y/N finds themselves drawn to Rick in a way they never expected. In a world where love is a weakness and trust can get you killed, can Y/N let their walls down? Or will the unknown survivor remain a ghost, even to the man who refuses to give up on them? Warnings: Violence, gore, angst, slow-burn romance, emotional trauma, post-apocalyptic survival themes.
