Maybe she thought that she's not worthy to be with emperor now. Maybe because she is already tainted (she became his brother's concubine) issues of her becoming an empress will rose up to the nobles you know nobles have so many complaints in life they even complaint the matters of other people. You know. Why don't you just take their own matters? Why they meddle so much? Right?
he actually killed everyone for a girl that already belongs to his brother, yet he's still not with said girl. emperor has a sad life.
