Cultural relic restorer An Yu received a special task: to restore cultural relics at the site of a girls' school in the Republic of China. In the dusty attic, she found a diary that had been deliberately hidden, recording the failed "moonlight appointment" between the headmistress Lan Yue and the music teacher Su Wen.
History scholar Lan Ya breaks into her world - this academic elite with gold-rimmed glasses is the great-granddaughter of the diary owner Lan Yue. A restorer who is obsessed with "fixing history in a perfect state" and a rebellious scholar who is committed to "tearing apart the disguise of history", from tit-for-tat to forced cooperation. The brass key in the secret room points to the forbidden secret of the Lan family's ancestral home.

When developer Lin Shicheng began to obstruct the investigation, and when the cultural relics restored by An Yu were damaged one after another, they discovered that the tragedies of Lan Yue and Su Wen were happening again.
What you restore is a cultural relic, but what I want to restore is tampered history.
If the truth would put you in danger, I'd rather never solve the mystery.
