On her twenty-eighth birthday, Cheng Jianqiu receives a letter from ten years ago.
The sender is her eighteen-year-old self.
It says: "If you still remember me, don't trust the summer you remember now."
For ten years, she has believed that family opposition, financial pressure, and betrayal by her best friend made her give up art school and miss out on the life she might have had.
But as one old letter after another arrives, she discovers that her memories are being overturned. Her friend never betrayed her, her parents never truly stopped her, and the withdrawal statement bears her own signature.
Harder still to accept is that perhaps she was never some undiscovered genius.
She is just an ordinary person.
And ordinary people deserve to decide their own lives.
