I had a dream. In the dream, I was the false heiress, and the true heiress came to the door, and she was reborn. She took my hand, weeping about how my birth family favored sons over daughters, and told me to stay with my adoptive parents. I believed her. Later, I ate the cake she offered and was struck with stomach pain, and performed terribly in the college entrance exam. My adoptive parents gradually grew distant, suspecting I was untrustworthy. When I woke up, I dismissed the absurd dream as nonsense. But the night before the exam, I watched the girl standing at my door, and fell into deep thought.
