Rinfu, whose father is an ambitious right chancellor, is forced to choose between becoming a decorative concubine in the harem or marrying the son of a rival family. Reluctantly, she participates in the 'Empress Selection Ceremony.' There, she meets the chief minister, Canglian, who recognizes her skills in childcare and erhu playing and orders her to become a harem official. Her duty is to take care of the young emperor. 'This way, I won't have to marry anyone! I'll work with all my might!!' Freed from her father's control, Rinfu begins to work with enthusiasm. This is a romantic comedy about Rinfu's fulfilling life in the harem and the slow-building relationship with Canglian, who is competent at work but clumsy in other aspects.
