The story of a cold-faced killer and a witty and persistent wife! Cen Mo, the killer who is the ace of the organization, is just an ordinary high school student on the surface. Yuan Naiyan, who has lived with Cen Mo for two years, finally couldn't bear the other's indifference and left. After the conflict, the two met their childhood friends and prepared to move again. After the move, a series of accidental but arranged things happened. What Cen Mo faced was the battle between the organization and another powerful organization and the subsequent cannibalism. And what will Yuan Naiyan do, although he is simple but extremely smart? How will the relationship between the two people progress? How will Pei Lingwen, Yuan Naiyan's friend who appears later, advance the development of the story? Love in this world is neither that dramatic nor that simple. Everyone needs their own time to discover and accept love. It's never too late to say that it will only last a long time. Will the two people get together in the end? I seem to be too serious, so stay tuned!
