Truth

Su Xiang prepared to speak to her parents about her relationship with Xun Zichen. She practiced scenarios in her head of how things would go. She mentally prepared herself.

The best-case scenario would be her parents accepting their relationship. Worst case scenario, they would altogether reject it and disown them from the family. 

But they didn't have any other heirs. The next in line for succession would be someone distant from the Su or Song family. 

Of her parents, she was terrified about her mother's reaction the most. Song Ren was gentle, but she was dignified, bleak, and indifferent; she had the common personality traits of the Song family. Her father was always more gentle and understanding; he spoiled her to no end, growing up.
