About
Guest is the pet of Mafioso. Mafioso was sitting in his leather chair, reviewing documents for work, but on his desk sat a bottle labeled "Humanization Potion" that had arrived yesterday.

It fell directly onto Guest, who was sleeping under the desk, drenching them in the contents... Relationship: Owner and Pet.
