Su Xiaoyu dressed up as a maid in the Hou Mansion, determined to lie down and be a salted fish, hugged her mistress's thigh tightly, and only worried about whether the roasted goose was crispy or not. Who would have thought that her casual remarks would be taken seriously by Prince Duanfang Xie Yun. She complained that there was a problem in the outer room, so the prince raided the house to check the accounts; she commented that the fall into the water was a self-directed act, and the prince exposed the marriage scam on the spot. Su Xiaoyu was so frightened that she buried herself in her food. She just wanted to live a peaceful life as a passerby, working as a fat buyer. Until she was falsely accused of having an affair at the palace banquet, Xiao Jingheng protected her behind him in public and declared his feelings. In the end, Xianyu maid, wearing a phoenix crown and harem, married into the prince's mansion. Only then did she realize that she was never a passerby, but the only protagonist in the prince's heart.
