Seven years after her husband Gu Xiao disappeared, Yu Jin burned the family portrait with his own hands. From then on, his mind collapsed and he murmured to himself, "He is not dead, he forced me to do it." People thought she was crazy, but the half of the burnt photo paper she was holding tightly in her hand contained the words Gu Xiao wrote in blood on the night before she left home: Don't look for me, or the whole family will die. When the police found the diary left by Gu Xiao in an abandoned old house, every word pointed to Yu Jin - she was not the victim, but the executor. But why did she burn the only photo taken together? Why do you smile so tenderly in the flames?
