Ri En's sister was found to be pregnant with Shun Shin Kun's child. Ri En, Shun Shin Kun and the king then planned to make this child the king's child so that the king's brother (whose deviant and erratic traits would bring Chu to ruin if he ruled) will not become the new king in the future, even if that means putting someone without the royal bloodline on the throne.
However, just before the death of the king, Shun Shin Kun changed his mind and wants to let the king's brother ascend the throne instead, and since it is too late to change their plans, as revealing the secret will result in death to all parties involved, including himself and his sister, he had to kill Shun Shin Kun, also both Shun Shin Kun and him sent assassins to kill each other, but only he survived.
