For a father, what more would they want more than watching his kids living happy and healthy lives in front of his eyes?
No matter how strong the Emperor is, in front of his family, he too was just like any other normal Father.
He too would want to see his son living healthily and happily in front of his eyes.
He was not worried about any of his other kids except this Fifth son.
He is not just sickly but would always speak the words that always expressed his lost will to live.
The Emperor did so many things to encourage him but in the end no matter what he does, he couldn't change his son's outlook on his life.
When he first asked his son to get married, Wang Deming refused immediately saying he doesn't want to waste the life of an innocent woman.
No matter how much the Emperor tried to convince him, he did not budge even an inch.
