My husband returned from a business trip for three months, but his five-year-old son quietly asked, "Who is the uncle in the bathroom?" Weird messages popped up one after another on WeChat, shrouding daily life with layers of fog. Everyone around him is weird, his son repeatedly denies his identity, and even the calls to the police contain terrifying twists. She thought she was suspicious, but she didn't know that she had already fallen into a fatal trap. When everything familiar becomes unfamiliar, who is trustworthy? What kind of terrifying truth is hidden behind this identity mystery?
