Zhou Xu, who had just graduated from college, suddenly received a call from his father.

“My son, since you have grown up, there are some things that a father should tell you.”

Zhou Xu: “Dad, how do you speak in a succinct manner? Half white or not, what TV series are you watching?”

“My son, it’s a showdown for my father. For my father, you are a giant of the devil. You are the son of the devil.”

Zhou Xu: “…Dad, I’m hanging up, I’m busy.”

“Wait, there’s one last thing. Aren’t you too young? Your mother arranged a blind date for you. See you.”

Zhou Xu: “Who is it?”

“Like you, the devil goddess at the opposite door.”
