It was a meticulously planned feast for the powerful. Her fiancé had knelt down on one knee and proposed to her sister instead. Robbed of her right to her inheritance, she was prepared for the Xi family to throw her to the wolves.

The Most Loving Marriage In History: Master Mu’s Pampered Wife

The two of them gaped at each other. They had no idea what was happening!

Who was that woman calling Xi Xiaye "Missus" just now?

Xi Xinyi thought about something and her pale face started to have an odd expression. Her eyes looked as if she had just witnessed something impossible. Without caring much, she started chasing her sister.

Huang Shanshan quickly caught up and they felt as if they had just experienced an auditory hallucination.

However, Xi Xiaye's figure was nowhere to be seen. The crowd almost drowned them as they tried to look around and still could not find her in the end. It was as if whatever had happened earlier was just a figment of their fantasy.

Huang Shanshan halted in her steps and asked as she was panting, "Xinyi, did you hear what that woman called Xi Xiaye? She seemed to have called her Missus, didn't she?" She turned around and looked at Xi Xinyi with flushed cheeks.
