On the eve of Mother's Day, the 23-year-old female college student went home early to surprise her mother, and unexpectedly found a huge bankbook in the drawer of her parents' bedroom. The account holder of the passbook is her mother. She has deposited 440,000 yuan on the same day every year since her birth date, accumulating more than 10 million yuan in 23 years. What makes her even more horrified is that the note in the bankbook says "To my precious son Haohao", but she is an only child. The heroine began to deal cleverly, collect evidence, and go to the appointment on her 24th birthday. Finally, with the intervention of the police, she exposed her parents' conspiracy and took back her own life.
