Tht kid princess is the one they were talking about being born when Tasara was 12 , he will be killed if she borned but she turn out not the blood of royal only tasara is the one left with royal blood , as king and tasara both knew that this kido is not their blood.
The princess is the Queen's daughter. She's not blood related to the prince at all. Tasara's mother killed herself when she knew about the curse. The king and Prince Tasara are the only royal blood left.
Nara was the empress and the princess was Tasara's daughter. I'm confused. Why do they look like Nara?
