(Heartbreaking + tragic + campus life) Yu Nian’s childhood is filled with loneliness and exclusion. Her family and the keepsake dolls she sews herself are her only comfort. But fate shows no mercy. In 2019, her father dies suddenly, and her mother passes away after surgery for an illness. In 2020, cancer takes her grandmother and younger sister one after another. With all her loved ones gone, she sinks into depression, trapped in endless darkness.
Then the boy Zhang Xiang enters her world. He is neither prejudiced nor distant, but quietly protects her and gently stays by her side, gradually healing her broken heart. He becomes the only glimmer of light in her bleak life. They fall for each other and promise to pursue the same future.
After reconciling with the past and finding redemption, they both choose to become undercover police officers after the college entrance exams, staying true to their original aspirations and standing side by side. But fate has other plans. During a dangerous mission, Yu Nian can only watch helplessly as the person she loves most dies in the line of duty.
She has no family left in this world, and Zhang Xiang is no longer by her side. For the rest of her life, she is alone, holding on to memories and keepsakes. In the long years of solitude, she never forgets, and the rest of her life is filled with regret.
