Fashion blogger Tang'er died suddenly and time-traveled to Daliang, becoming the hair-combing palace maid of the out-of-favor imperial concubine Shen Zhaoning. To save her life, she used modern aesthetics to alter the concubine's makeup and clothing, helping her regain imperial favor and helping the eldest princess escape the suppression of the Lu residence. After being promoted, Tang'er became entangled in the old grievances of the empress and the mystery of the third princess's premature death, and also saw the loneliness behind the concubine's pride. The concubine gave birth to an imperial prince, and Tang'er encountered the seven-star alignment when leaving the palace, returning to the modern era. Facing the Shen Zhaoning Memorial Hall, she finally understood that this time travel was a thousand-year redemption.
