This novel tells the story of a middle-aged urban professional who, struggling with depression, loses his job and his marriage, but refuses to bow to fate and rises again. In the bustling city, the Jing'an Yayun residential complex seems peaceful, yet undercurrents swirl beneath the surface. The protagonist, Mu Jianguo, is mired in depression. The nonstop noise from upstairs cuts at his fragile nerves like a blade, making his condition worse.
He seeks medical help, attends psychology lectures, and tries to talk to his neighbors about the noise, but meets with repeated setbacks. In a fast-paced city, mental health is ignored, and neighbors are cold and distant, leaving him increasingly helpless and despairing, to the point that he even considers taking his own life. Around him, too, are lonely souls crushed by the weight of daily life, each struggling in their own way...
Just as the protagonist is on the verge of collapse, a mysterious stranger he happens to meet shines a faint light into his dark world. But fate does not show him mercy for long, and one blow after another soon follows...
This novel offers a profound reflection on urban indifference and the neglect of mental health. Amid the clamor of the world, salvation for lonely souls may lie in understanding and connection, so often forgotten.
