A group photo of seven people was taken, with the sister standing on the far right.
Shen Yue discovered this photo while sorting out his mother's belongings. He checked the identities of six other people and found a surprising pattern: from right to left, one person disappeared every few years. The first was fifteen years ago, the second was ten years ago, and the third was five years ago. My sister is the fourth, seventh year.
There is a line of vague words behind the group photo: The seventh is the end.
Seven people all lived in the same place - Moon Bay. In that old residential area that is about to be demolished, there is a secret from twenty-three years ago. Shen Yue must find the source of all this before the next disappearance occurs. But as he digs deeper, he discovers that his sister's disappearance was no accident - she disappeared of her own accord.
She is protecting him.
"The seventh is the end" - this sentence has two meanings. Now, Shen Yue is going to uncover the real answer.
