When she was a child, Jiang Ruotao was close to the boy next door, Shen Yi. But the Shen family moved away overnight, and there was no news from Shen Yi.
When they reunited in high school, Shen Yi was particularly close to her, but Jiang Ruotao noticed that there was a secret hidden in his eyes. Those hesitations to say seem to be closely entangled with the truth of their farewell without saying goodbye.
On her 18th birthday, she received a scheduled text message from Shen Yi. The moment the text message was sent, the boy disappeared like the morning mist. What kind of secret is locked in this unopened letter? Why did the people who left without saying goodbye choose to disappear again after meeting again?
