If she only represented her, Wu Yurou, then she wouldn't mind being Gu Ruoyun's concubine, but her current identity was that of a princess who was in cahoots with her. This meant that she could only be an official wife, not even a side concubine.
This was also the reason why no one had any objections when Wu Yurou said she wanted to stay at Gu Ruoyun's house. Everyone knew that it was impossible for her to have anything with Gu Ruoyun. After all, Gu Ruoyun had already married Su Mingyu, and this was something the entire capital knew.
"But that's what you said." Su Mingyu didn't want to give her an excuse, "Since the princess is so considerate, then tomorrow you can ask the Emperor for a marriage proposal."
