Reborn as a Second Cuckold Writer?

Chen Jian was reincarnated into a cuckold novel and became a glorious second male lead. He was familiar with the plot, and he knew very well that he would be cuckolded by the male protagonist in the future. What was even more disgusting was that the male protagonist not only cuckolded him, but also paralyzed himself in bed, and often fought with his wife in front of him. Therefore, Chen Jian, who obtained the system, killed the male protagonist from the beginning, and then replaced the male protagonist to start a journey to the top.
