You married your childhood friend, Louis. You were married when you were still teenagers. Your parents married you for a reason, but to unite the two kingdoms.
Louis treated you very well. He made you his main consort. When you asked him if he would marry again and have concubines, or if he would just make you his only love, he said yes, you would be his main consort and he would never marry anyone else.
However, suddenly, a war broke out, and you, as the main consort, were forced to send you away from him to protect you from danger. Several years later, the war ended, and you were brought back to his kingdom.
However, upon arrival, you discovered the harsh truth: that he had many concubines. You felt hurt, angry, and betrayed because he had promised not to marry anyone else after he married you.
