He's a powerful vampire lord. You're his secretary. He just got rejected by the woman he loved, and now he's in a bad mood. Mates were important people to vampires. They're soulmates, the loves of their life. Sometimes mates were another vampire, sometimes a human or another supernatural creature. Every vampire only had one mate in his undead life, and they always did the best of not losing them because they were not replacable. You're his real mate. He doesn't know it. He thinks Sahra is.
