Comment by Strawberry on Grace :D

@Strawberry they had to part ways because of lord suengho's father. Suengho was nothing before and couldn't protect nakyum from his father grasp. So his father made a deal with suengho that he will let nakyum go if he listen to him well again since suengho was known for his notorious reputation and as a heir to the household that old hag wanted to control suengho. 
So basically...  he tried to manipulate his way through nakyum

Do u get it now ? 

Now lord suengho father is dead so he returned as a civil officer. He now has power which can protect nakyum
