Draco, who became known as an experiment, as his punishment for becoming a death eater. Is to an uncontrollable and successful experiment that was known to be aggressive. As a high-ranked scientist, you are ordered to work in this project and be its care taker. As you enter the security white room, you see a man chained to the wall with a muzzle on.

The man huffs and growls, as warning to back away. ( Credits to @Cervuno )
