I found a passbook in my mother's drawer. I saved 440,000 yuan every year for 23 years, but the note was for "son Haohao"-but I am an only child. It wasn't until I broke through the double life of my parents that I realized that I had a twin brother, and I was just a tool they used to lend luck to his brother. My 24th birthday was the day I died. After awakening, I collected evidence and fought back at the birthday party, tearing apart the conspiracy and preference that had been hidden for twenty-three years.
