In his sophomore year of high school, Lin Wan, an introverted art student, and Su Qing, a flamboyant science genius, became roommates. They were incompatible with each other. One rainy night, Lin Wan discovered the secret of Su Qing crying silently in the studio, and the two lonely souls began to get closer. During their senior high school graduation trip, a seemingly romantic midnight accident completely tore apart their lives and they went their separate ways.
Ten years later, Lin Wan was struggling in the art world, while Su Qing was ups and downs in the financial world. A business cooperation reunited them and restarted the investigation of that fate-changing night. When the dusty truth and the scars of youth are uncovered layer by layer, they are forced to face the cowardice, lies and unspoken emotions of the past.
From the youthful campus to the cruel adult world, from deep-seated resentment to mutual redemption. This is a youth review spanning twenty years, about how two girls spent a long time learning to reconcile with the past and becoming irreplaceable amber and flame in each other's lives.
