But being with the Crown Prince is different.
The Crown Prince is still so young, have very few offspring, only a son and a daughter. The women around him, apart from the Princess Consort, are just Concubine Li and Jin Liangyuan.
Concubine Li has been with the Crown Prince for many years. If she could get pregnant, she would have by now. It's clear that her health is not up to par.
As for Jin Liangyuan, a foreigner, she's merely a toy gifted by Silla to please the Crown Prince. No matter how beautiful she is, no one would take her seriously.
With her status, even if she were to give birth to an offspring, it wouldn't be given much importance.
All things considered, only the Princess Consort in the East Palace is of any importance.
If I don't use this opportunity to push our exceptional daughter into the East Palace, then what am I waiting for?
