The moment I was hit by a retrograde truck, I thought my life was over. Unexpectedly, when he opened his eyes again, he found that he had become another person - and she was the woman who cried the most in the hospital. Now she had my body and I was trapped in her identity. Her husband calls me wife, and her children call me mom, but there is a love letter she wrote to another man hidden deep in the closet. A joke of fate, the truth behind the car accident, and behind this body exchange, was it an accident or someone who had planned it for a long time?
