Don't Pull the Demon's Tail

Demetrius works at an organisation called 'The Office' who specialises in exorcisms and fighting all things supernatural. During a fight with a demon, in order to save his manager Zayden, he has to reveal that he is in fact a demon himself! 'The Office' allows him to keep his job as exorcist, but only if he swears a partnership pact with Zayden. So after teaming up and being together 24/7 they start to develop feelings for each other, but is a demon's feelings only lust?
