At two o'clock in the morning, Xuan Xu browsed the friend circle of his wife's best friend, and the picture showed two pairs of slippers. He closed his eyes with a smile, and opened the dead man's phone that night, only to see the scene from that night - his wife was at his best friend's house, and there were a pair of men's shoes next to the slippers. The next day, my best friend died naked in the bathtub. The police concluded that it was an accident. My girlfriend cried heartbrokenly. But Xuan Xu knew - last night, through soul induction, he saw with his own eyes the "it" left by his best friend worming its way into his girlfriend's shadow. Tonight, he received a new corpse reminder: the girl who sent the text message noted "husband", and the avatar was actually him. There are only four words in the prompt: Run away. Don't believe her.
