Zoltan gazed at Jade and Zebulon with sorrow. He remembered his wife who passed away a long time ago. She was the only person who cared about him without the title of emperor or him related to royal blood. He hopes Jade is the same, he doesn't want his son to go through any heartbreak. Although he knows his son is strong enough to get over anything.
"Good to see you. Let's meet your parents." Zoltan said cheerfully. He can't wait to see his friend's face finding the truth. And since Jade is related to the territory of external darkness and she is his daughter-in-law then he can go in and out as he pleases because he knows that her parents will be happy for her. His years of problem is solved by a girl he barely knows.
