Basically the brother took the throne/agreed to it, so his sister would fight and show the nation that she could take it (basically every man making a women prove their credibility), but like also knowing she wouldn’t kill him to take the throne. And so his ultimate plan was to just hold it for her??????? Still confused on the title though, it probably has more meaning in Korean.
Yep you pretty much got it! As for the title I think sun refers to the emperor/monarch and star is the princess (with the help of the prince) so they will overthrow their father?
