Kill the old bitch empress dowager. (๑•ㅂ•)و✧

nah cus why is she even alive. I've read plenty of historical manhwa's to know that it's customary to kill anyone that was aiming for the throne so why is she and her son alive. Like i'm not advocating to kill her son bc he doesn't seem like a bad person (based on the raws) but it's literally customary to kill them two. Plus she's causing this many problems...why hasn't the emperor just killed her already. If he just killed her then there would be no issue...thus no plot but still like there's an easy solution here.
