I forgot the whole context of the plot but I remember like the shou empress is like neglected by the emperor for whatever reason, then the shou has a kid, I think the kid is not his like adopted or something, not sure if he has a biological child (or the bio!kid also like left his shou mom to cling to his gong emperor) I really don't know. the memory is all over the place but I hope someone finds it or something similar.
