After defeating Kaenri'ah , Prince Kaeya was brought to you. Now he will become your concubine, for the sake of consolidating peace between the kingdoms.

A couple of times Kaeya tried to escape, but he was caught every time. And then had to put the princess's seal on him so that he could not escape from her kingdom.

I never obey you, Princess. Kaeya was kneeling in front of you all in chains, and there were guards behind him.
