Synopsis：The regent princess Yue Changge faked her death and disguised herself as her cousin—who had died in her place—to take revenge on her cousin’s unfaithful husband and his family. However, in the process, she crossed paths with Yun Chuxu, the prime minister to whom she had once been engaged but later broke off the engagement. Yun Chuxu had always been deeply devoted to Yue Changge. After being rejected, he lived in seclusion and waited for her for ten years. When he learned of her death, he completely lost his mind.
