The only daughter of the Su family married into the Guhou Mansion. At that time, the Mansion was already empty and relied entirely on her generous dowry to support its dignity. After they got married, she gave birth to her daughter Nian'er, and she was determined to live a stable life, but unexpectedly, after Gu Yan rescued Lin Yue from drowning at the lotus appreciation feast, he hurriedly took a concubine, and even tried to seize her as a concubine and demote his wife as a concubine. Faced with the cold eyes of her mother-in-law, the sarcasm of her sister-in-law, and the callousness of Gu Yan, she always sticks to her heart, protects her dowry and daughter, and maintains the bottom line without being humble or arrogant. In the end, the Guhou Mansion gradually declined, and she lived a stable life with her daughter Nian'er. Nian'er also successfully inherited the title of the Marquis Mansion, and the years to come were peaceful.
