Can you recommend a novel with a cold-blooded male lead?

The title of the book was something that he had forgotten for a long time. The male protagonist was extremely cold and merciless when he killed people. The female protagonist was willing to give up everything for him. This book isn't like the male protagonist who was touched at the end. I remember that the male protagonist was very young when he joined the assassin organization and was " cut " into a eunuch. So feelings will only become the key to his perverted slaughter

Answer 1

I recommend "The Scapegoat Bride of the Cold-Blooded Emperor" to you. The male lead is cold-blooded and heartless, while the female lead refuses to give in for the sake of her self-esteem. However, she is treated even more ruthlessly by him. Because of a shocking secret, they are once again pushed into the bottomless abyss. I hope you like my recommendation. Muah ~
