Lin Jianwei was born with a cold ability: he can foresee the moment of death of others. As a result, she alienated herself from the crowd and lived like a bystander until she "saw" the newly moved blind pianist Shen Tinglan, who would be murdered a month later. Even in the darkness, that man was as gentle as a beam of light, quietly knocking on the closed door of her heart with the sound of his piano. Lin Jianwei, who originally wanted to watch indifferently, had the idea of changing his fate for the first time - she wanted to use foresight as a blade to become the only variable in his death fate. When the conspiracy came as expected, she stood in front of him, but was tightly protected in his arms. He couldn't see her appearance, but he understood her loneliness: "Don't be afraid, this time, I will be your light." This is a story about the "accident" of a prophet and her, rescuing each other and running in both directions in a script that is doomed to tragedy.
