If You Want to Frame Me as a Vilainess, I Will Be the Vilainess. However

I, Christiane, am the fiancée of the Crown Prince of the Zebia Kingdom. However, at the party meant to celebrate my graduation from the academy, I find myself accused of wrongdoing by my fiancé, Fabian. Beside him, clinging to him with a frightened look, is Baroness Noelia. Lowering my head, trembling slightly, I lift my face to meet their gazes. To become the villainess.
