Su Qingyan married into Prince Jing's palace, but she was just a masked princess fulfilling her sister's contract. Her husband Xiao Jue is cold-faced and unfeeling, but when she gets along with the gentle young man Gu Yunzhou, he always gets jealous and causes absurd farce. She originally wanted to endure the three-year engagement and get out, but she was repeatedly bullied by the slaves in the palace and framed by her concubines. When she was abused physically and mentally, Xiao Jue always acted in secret and refused to show any tenderness. Su Qingyan saw through this fake relationship. She did not love the wealth of the noble family, did not ask for her husband's pity, and opened an embroidery workshop on her own, broke old grudges, and earned her independence in a world where men were superior to women. When Xiao Jue lowered her guard and Gu Yunzhou lovingly protected her, the entanglement that started with Mask was ultimately decided by her - what she wanted was never anyone's preference, but the freedom to control her own life.
