Shen Qingci, the concubine of the Shangshu Mansion, relied on her cleverness to avoid trouble in the back house. However, she accidentally got involved in the "old Shanguan case" because of her cold-hearted attitude towards the Marquis Xie Yunlan.
She exposed her sister's plot and searched for the account books of the secret passage in the medicine garden. He broke the star pattern code and protected her from danger. The two went from investigating crimes on the streets of Chang'an to making wishes at the lanterns in Jiangnan, running in both directions amidst conspiracy and warmth.
When the old case was revealed, the red candle reflected the double happiness, and Shen Qingci realized that the warmest place in Chang'an was the cold-faced Marquis who spent his life turning her "drama queen" daily life into a long-lasting gentleness.
