My mother-in-law, Miu, is a longing existence for me. The moment we first met, I fell in love. One day, transportation was stopped due to a record-breaking torrential rain, and my father became a refugee returning home. Alone under one roof with my longing Miu, wet hair, transparent underwear, and a torrential rain that is becoming more intense, I couldn't suppress my desires, so I hugged Miu, who was shivering in the cold, even though I knew that it was no good.
