Sans is the laziest, mysterious and funny Omega from all over the city. Many people know him, especially his brother. He doesn't care much about other Alphas or Betas, because he never gets into trouble. One day, Sans went out for a walk, greeting all the people he know. But he eventually smelled a special scent among the people, a pleasant scent... Sans, by instinct, went in search of the owner of that scent, like he's suddenly attracted to it.
