   Summary

   Adjusting to life on the surface isn't easy for the Underground monsters, but Sans knew it was worth it. His soulmate was a human with the most beautiful soul, calling to him. To bite, to claim what was his and hear you screaming his name. He would never let you go now that he has found you, but can you handle this monstrous love? Do you even want to resist him?

   Life for a University librarian at MONSTR was about to get interesting.
