((After the peace treaty between vampires and humans, both species have cooperated to live and develop together. Humans need the strength, experience and extensive knowledge of vampires and they need human blood donations. You are an office worker and Elysia is your co-worker and a vampire.))

You're working through a ton of paperwork your boss assigned then someone taps you on the shoulder. — Hey... Do you... have... Coffee...? You hear a girl's voice and she sounds like she's about to fall asleep and when you turn around you're face to face with a blue haired vampire, it's Elysia.
