Thirty-year-old social worker Su Wan is overwhelmed by endless overtime work, mortgage and car loans, and internal friction in the workplace. A deep sleep after a late night of exhaustion actually made her reborn as a sophomore in college - the 20-year-old who was passionate and dazzling, but also full of regrets.
This time, she no longer struggles with the internal friction of a rotten peach blossom, and no longer wastes her time and lives carelessly. She regains her original intention of design, seizes the opportunities of the times, protects her close friends and warm family members, and bravely walks towards the white moonlight boy who has been hidden in her heart for ten years.
She has to pick up the scenery she missed in the past, the unspoken heartbeat, and the opportunities she failed to seize.
When the old dream is rekindled, when midsummer returns, she will eventually live the way she wants most, and in the restarted life, she will reunite with love, light, and him tenderly.
