Spoiler The truth about Consort Taizhen (The Human Emperor)

What is the truth about Consort Taizhen? Why is she a virgin? Why did King Shou marry her and then the emperor steals her from his own son?

 

Nothing in the raws yet I don't think I might of missed it tho

 

Spoiler: Consort Taizen

You probably missed it, I dont know the truth either
But i can tell u, the incident first mentioned at chapter 85
at chapter 103-104 we saw her meeting with her little cousin.
At chapters 119-128 Mc writes her a poem to calm her down(Cause king song was forbidden from attending meeting at the royal palace due to him opposing the emperor)
I read until chapter 128 and quit.
Cause the story isnt my cup of tea.

 

I meant nothing about his qestions I don't think there answered in the raws yet

 

Are there any official (historic) records, does anyone know?
