Wang Yiyi fell down and hit her brain, and she had a memory that didn't belong to her. She saw that her sister who was rushing to become a stepmother regretted it. She wanted to get out, so she wanted her to fill this hole. She saw her sleeping with her brother-in-law for no apparent reason because of being drugged, and then her sister divorced her because of seducing her brother-in-law. Then she became a stepmother after her sister's divorce. She felt guilty for causing her sister's marriage to break up, so she devoted her life to her brother-in-law's family without any regrets, and worked hard to raise her children. In the end, she became old and useless, kicked out by her step-children who were not related by blood, and finally froze to death on the street.
After reading the memory, Wang Yiyi... Is she the kind of person who dedicates her life to others without any regrets? It's not her place to hold such grudges, she should take them on whomever she loves!
After waking up, Wang Yiyi made up her mind not to be a resentful person and stay away from all people and things that might make her a resentful person. No one would want her to fall into the trap.
Wang Yiyi later learned that she, the heroine in her memory, and her brother-in-law's eldest daughter all had a memory that was not theirs. According to modern terms, they were familiar with the plot. However, the plots in their hands were not genuine plots. What they read were all fanfics, or fanfics created after the magic transformation...
