He accidentally abuses his wife. It feels good for a while, but he unexpectedly picks up a treasure of a medical concubine. "Your Majesty, I like the moon in the sky"; "Be good, I will pick it for you"; "Get away from the dog man, Yingying Yanyan, I feel dirty"; "I am so hurt, there is no one else but you, my beloved concubine, please give me a hug."
