After My Sister Cheated on Her Art Exam

Before the art exam, my cousin complained to me that practicing dance every day was too hard, and wanted my parents to help her connect with people and enter the top-ranked school in her major. I refused her decisively and strictly supervised her dance practice so that she could use her strength to get into the school of her dreams. But after she gained fame and fortune, she backhandedly caused the tragic death of our whole family. She also said, "If you hadn't let me go, how could I have had such a hard time!" When I opened my eyes again, I went back to the day when she complained to me that practicing dance was too hard.
