Copy 1: 28-year-old Lin Xi always feels that there is a missing corner in her life. This may be the reason why Lin Xi has been single until now. This corner may have been missed, or it may not have appeared yet; she returned to the second year of high school overnight. She is only 17 years old this year, and she is in her youth. Copy 2: Lin Xi, 28 years old, has a house and a car, but is still single; after returning to her second year of high school, she didn't know why God allowed her to go back to this time. She felt that although her youth had some frustrations, it was generally okay; until she met him who did not appear in her original life trajectory, she seemed to have found the answer.
