"Child, p-promise me that you will never hate your grandfather. It's not his fault why I am in this condition."
"Father, how can you still say those words to me? Grandfather let you stay in this cage like a wild animal yet you want me to do that?"
"Yes, my child. If you will promise me to do that, and to be a great king someday, even greater than your grandfather, I can die peacefully and lives with the heaven."
"Father..."
"Yang, go to my office. In the box where my drawings were stored, you can find a painting. Take that with you and give it to your grandfather who was currently outside the palace. He went out to hear the grievances of our people. If you give that painting, he will surely understand what are my intentions."
Yang was about to say more words to his father, the crown prince of the kingdom, but he can't do it anymore. Because the palace guards who are patrolling are coming.
"Go now, Yang. Don't let them know that you visited me here. In my condition right now, you will be graded as a traitor too. Don't forget your promise, my child."
With his eyes that full of crystal balls, Yang was forcefully stepped out from the royal court yard where his father the crown prince was imprisoned in a cage.
