If you could go back to seventeen years old just by blowing out the candles, the price would be to experience death over and over again, would you be willing?
Twenty-six-year-old Lin Wangshu is a wandering shadow in this city made of steel and concrete. She goes to uninteresting classes day after day, has no friends, no relatives, no social interaction, and lives a mechanical life.
On her twenty-seventh birthday, she received a mysterious cake. Blow out the candles on the cake and you can go back to the night of your seventeenth birthday. At the school anniversary party the next day, a fire broke out in the school auditorium, causing Lin Wangshu to lose forever her caring teacher, best friend, and the boy who smiled like the blazing sun - Jiang Chaosheng.
Even if she has to face the fear of death again and again, even if she has to face her lover and friends who know nothing about her every time she opens her eyes, she still has no hesitation.
During the 24 hours that she went back to the past and cycled continuously, she discovered that her youth contained so many undiscovered secrets. All the love and regret buried in the ashes finally see the light of day again.
