Wei Zi is pregnant, and Erkang cares about Wei Zi.

Your Majesty, Wei Zi's life is very important to you, and so is her blood relationship. Birthday is very important, but she means nothing to me. I value and love her, not because she is a princess, not because she has royal blood, but because she is the only Wei Zi in the world! She is the daughter of a criminal, a rogue, a beggar and a murderer. She is still my crape myrtle, and my feelings and appreciation for her will never change at all because of her identity. The life and wealth exchanged for crape myrtle are too small for me!
