Thirty-one-year-old social worker Lin Wanxing, who spent half his life working endless overtime and making things difficult for his employer, suddenly dreamed of going back to his sophomore year of high school in 2009.
Returning to the midsummer day when she was seventeen years old, she returned with memories of fifteen years and full of regrets.
This time, she wants to stop her best friend whose family is in decline and is forced to run away; to protect her grandmother who is in pain and passed away early; to wake up the young man in the backseat who is living in confusion and has a precarious future; and to resolve the appointment with Su Lin that was half a lifetime late.
Once upon a time, they were pushed apart by time and became silent avatars in the address book.
Now, time turns back and years come back again.
Lin Wanxing stood in the seventeen-year-old wind and secretly swore:
If we go back again, old friends will not be separated, no regrets will remain, and everything we love will be fulfilled.
