The Possesive Tyrant and His Sleepy Cat

Story:

I'm a cursed cat stuck in a mature-rated book whose very existence is seen to be detrimental to the empire. Because of one prophecy, this place has murdered every cat in every alley. My time on this earth will end the instant someone discovers me. "What's this?" The male lead, who is destined to become a crazy tyrant, easily grabs hold of me before I could even consider running away.
