In the first year of Jingyuan, Gu Yan entered the court following the late emperor's imperial edict to assist the young empress Lu You.
For the next twenty years, she blocked all undercurrents for Lu You and quietly pulled out the roots that threatened him, never making any announcement or letting her know.
Lu You relied on her, but was also afraid of her.
It's just the power that she can't admit.
So one day, she chose to give up.
Gu Yan knows.
She still didn't say anything, but when she left, she left the ebony hairpin she had worn for many years on the dressing table and rode out of the city alone.
