Shen Zhimian can enter other people's dreams and rid them of their nightmares.
In seven years on the job, she'd never encountered anything she couldn't explain, until seven people with nothing in common all dreamed of the same woman.
Black hair, a red umbrella, always watching her from the depths of the dream.
At their seventh meeting, the woman finally said her name.
"Shen Zhimian, you've forgotten me again."
Shen Zhimian was sure she'd never met her.
But at dawn the next day, when she returned home, the woman who should have existed only in her dreams was sitting outside her door.
She said her name was Pei Zhao.
She also said:
"I'm your ex-girlfriend."
Even stranger, there was no trace of Pei Zhao in the real world: no household registration, school or hospital records, not even a single photograph of her.
There was no evidence in the world that Pei Zhao had ever existed.
Except for the three years of memories in Shen Zhimian's mind, memories she had erased with her own hands.
Theme: Even when memories disappear, love and choices leave their mark.
