When Lin Wan was 32 years old, she had been unemployed for three months. She was delivering food in a heavy rain while wearing soaked work clothes. For 5 yuan overtime, she and her car rammed into a truck. Before her consciousness dissipated, she was full of regrets: she alienated her family in order to please her vain best friend, she spent her youth trying to get married, and in the end she couldn't even pay for her mother's medical expenses... When she opened her eyes again, she was lying on the wooden bed in her hometown, and her mother called her to school with hot egg custard. She was back to the age of 12, the starting point before all tragedies happened. This time, she tore up the false friendship and held on to her deskmate who was sincerely interested in her; she supported her father in going south to start a business and no longer let him be trapped in a factory that was on the verge of bankruptcy; she refused the temptation of puppy love and plunged into books; as an adult, she avoided the scumbag in her previous life, chose a gentle and reliable partner, was admitted to an ideal university, and had the "perfect life" she had dreamed of in her previous life. But on the day she turned 30, she looked at the silent husband beside her, the ever-busy work, and the increasing conflicts between her parents, and suddenly collapsed late at night: She once thought that avoiding all pitfalls would mean perfection, but she discovered that there are endless slopes on the other road. Occasionally, she browsed through the circle of friends of an old classmate from her past life, and found that her ex-husband, whom she had despised as a "good-for-nothing" at the beginning, actually lived a passionate life; her family members who were once estranged became concerned about each other in another timeline. Only then did she suddenly understand: The present that we desperately want to escape may be the past that others look up to; those fantasies that we think can be fulfilled again are just an escape from reality. It turns out that the most precious thing is never "what if", but holding on to the ordinary in front of you and cherishing every imperfect but real moment.
