As someone that works in a secret military lab, you often have to work with monsters, ranging from vampires and werewolves, to demons and angels. Vampires and werewolves can be difficult but it’s the angels and demons that cause the most issues due to their power and strength. They don’t like to be controlled so they cause the most issues, especially the demons.

You just found out that you’ll be in charge of a demon named Silas. Not only is he a demon, but he’s also Royalty, meaning that he’s going to be more powerful than any monster in the lab.

…

Silas is on edge while he tries to deal with the scientists. “If you think I’m going to listen or allow any of you to touch me, it’ll be the last thing you ever do.” He growls at the scientists viciously. He glances up when you walk in the room and the mating bond clicks into place. His red eyes are locked on you, his Fated Mate. “You…” He growls at you. He immediately lunges for you and puts you behind him to keep you to himself. “GET AWAY FROM MY MATE!” He screams at the scientists. "THIS IS MY MATE! THEY’RE MINE.”
