Back to 1980: The Day My Sister and I Swapped College Entrance Exam Scores

I got into a technical secondary school. My older sister, who had only gotten into a regular high school, stole my identity and went to the technical school in my place. Three years later, I used her identity to take the college entrance exam and got into an ordinary university. After graduating, I seized the opportunities of the times, started a company, and became a big boss. My sister, meanwhile, had long since become a laid-off worker, and her husband was disabled. She asked me to buy a house for her son. When I refused, she shoved me into the river. When I opened my eyes again, I was back on the day my technical school acceptance letter arrived. My uncle told me to give my place to my sister. But she turned it down herself, saying she would get into college on her own. I knew she had been reborn, too.
