On the night of the car accident, two girls were taken to the same emergency room. Their hearts stopped at the same instant, and started beating again at the same instant.
When she woke up, Su Nian was holding Xie Ci's hand. He didn't realize she wasn't herself.
The real Lin Wanxing had lost all her memories. She didn't remember who she was, but she hummed Chopin in the library and kept pushing open the same white door in her dreams.
Xie Ci noticed. Lu Ming noticed, too. But all they said was, "She's changed."
No one would ever think of that possibility. The truth was sealed in amber, and everyone was waiting for the faint sound of it shattering.
