My Sister Is the Empress Season 4

Plot Synopsis

The princess consort was full of grievances, her eyes reddening. She rushed to the third sister. Before she could even utter a word, tears welled up in her eyes and streamed down her cheeks. "Third sister, life in the prince's mansion is really unbearable for me. They actually framed me as a spy!" She sobbed, her voice choked with sobs. "When something was lost in the study, they immediately and without asking any questions accused me of taking it. I was really at a loss for words to defend myself."
