For Su Jianqing, a transfer student suffering from rare prosopagnosia, the world is a blurry sea of people. Until she met Jiang Che, the "transparent man" who always slept on the rooftop of the school - the only face in the school that she could clearly "see".
An oolong incident involving a "gamble" made Jiang Che her exclusive "face guide". From the initial awkwardness and perfunctory, to being accidentally hit by the story in her singing, two lonely souls found the only resonance frequency in the noisy campus. He showed her the way, she sang for him, and they pieced together the broken outlines of each other in the secret base on the rooftop that no one knew about. When a false bet meets real excitement, this two-way redemption of "seeing" and "being seen" has just begun.
