The heroine Liu Yunshu was originally the prince's principal concubine, but she was framed by her concubine Liu Yunxi on her wedding night. She lost her position as a principal concubine and was demoted to a side concubine. After Liu Yunxi became the concubine, she made things difficult for Liu Yunshu in every possible way and even wanted to kill the child in her belly. Liu Yunshu endured the humiliation, secretly contacted her family's forces, and received secret protection from the prince (the prince had already noticed Liu Yunxi's conspiracy). In the end, Liu Yunshu exposed Liu Yunxi's true identity (she was not the biological daughter of the Liu family), regained her position as the concubine, and her baby was successfully born, becoming the heir to the palace.
