The young wife doesn't know many people, and not many people would write to her. Neither the people in town nor the village would write to her, the only ones who might would be Princess Rui and the Commandery Princess.
Princess Rui had only written to her recently, so it was unlikely that she would write again so soon; that left only Princess Baolu.
Gu Ya thought the letter to the young wife was from the Commandery Princess of the Rong Residence and was surprised when the young wife said to him, "Husband, this letter is from Prince Chu!"
"Prince Chu?" Gu Ya's face immediately grew cold at the mention.
Su Yunjin nodded, "The maid said the person who delivered the letter left right after. I only found out it was from Prince Chu after reading it."
