32-Year-old Lin Zhan hit rock bottom on her birthday: she was optimized by a major company, her boyfriend of five years broke up, her home was sold, and she had to take care of her mother with Alzheimer's disease. Desperate, she moved into an old alley and met Chen Yan, a cardiac surgeon who was hiding in the city. Two broken souls redeem each other and serve as each other's lamps in the daily life of fireworks. The theme of modern urban reality, no golden fingers, no rebirth counterattacks, no hegemonic cheats, focuses on the survival dilemma, spiritual internal friction and self-reconciliation of ordinary people in the 30+ city. With "mutual healing in the smoke" as the core, it pokes at the collective pain points of contemporary people's workplace anxiety, pension pressure, collapse of intimate relationships, and wandering. It allows readers to immerse themselves in the realistic works of "this is my life".
