In her past life, the heroine was cruelly schemed against by her neighbours and sister-in-law. When she gave birth, they swapped her biological daughter and sent her to an orphanage, tricking her into depositing the five million in compensation her husband had earned with his life into her adopted son's growth account, locked until he turned 18. The heroine raised the child of her enemies for eighteen years, and on the day of his coming-of-age ceremony, she discovered the truth, fell critically ill from anger, and the neighbours even pulled out her oxygen tube, seizing all the compensation money. The heroine is reborn on the very day she just gave birth and instantly sees through the lies. She pretends to be unaware and deposits the compensation into the adopted son's account as the neighbours wish, while secretly plotting. For eighteen years, she never stops the neighbours from spoiling her adopted son, letting them claim the mother role and turn the child into a spoiled brat. On the night of his eighteenth birthday, in front of all friends and family, she reveals all the neighbours’ secrets, exposes the adopted son's true identity and unfilial behaviour, leaving the neighbours disgraced and penniless, and the locked eight million returns to her. In the end, she finds her biological daughter, cuts all ties with the neighbours, and starts a brand-new life.
