I recommend Baby Vengeance: Ruthless Daddy Killer Mommy to you. The male lead was a gentle and refined noble son who looked gentle on the surface, but in reality, he was the mastermind behind a bloodthirsty and cruel experimental killer. He was very cold when he was with the female lead, but he loved her deeply. The female lead was an assassin with the serial number AK-47. In order to escape from the male lead's hands, she risked her life for one last dangerous mission and finally left the male lead's side. This novel is a modern romance novel about wealthy families. I recommend it to you. I hope you like this fairy's recommendation. Muah ~😗
