A modern million-follower fashion blogger, Tang'er, accidentally time travels and is reduced to a low-level hair-dressing maid in the palace of the out-of-favor Consort Shen of the Great Liang Dynasty. Relying on her advanced makeup aesthetics and styling ideas, she helps Consort Shen step by step regain imperial favor, while also deeply probing into the harem's power struggles and past grievances, witnessing the joys, sorrows, and bonds of women in the deep palace. Coinciding with the celestial phenomenon of the Seven Stars Alignment, she returns to the modern era, only to discover that this cross-millennial encounter has long had a destined origin.
