**About the work:**
On Shennan Avenue, Lu Yao, a 22-year-old convenience store girl, met Gu Xingchen, a 16-year-old physics genius. A falling coin, a struggle on the edge of life and death, two lonely souls quietly colliding in front of the glass counter in midsummer. She was the double-sugar coffee delivered to him outside the provincial competition examination room, and he was the immortal oscilloscope fluorescence next to her father's medical record. They spent ten years spanning not only six years, but also the turbulent waves of the entire Chinese mobile phone industry.
When coffee stains in Xingyao Technology Laboratory soaked patent documents, and when the warehouse collapsed on a rainy night and buried an unopened wedding ring, Lu Yao made a bloody breakthrough in the male-dominated technological jungle. The sharp edge of sexism, the trap of commercial espionage, and the plagiarist colleagues could not erase the star of the engineer in her eyes - even if she had to personally burn the love letter hidden by the teenager behind the Orsay admission ticket, and even if she was stigmatized as treason in the smoke of the 6G standards war, she still guarded the chip stained with cherry juice and fought for the domestic screen at the IEC international standard revision meeting.
From the copycat machine repair shop to the Nasdaq bell-ringing platform, from the torn convenience store photo to the photonic communication holographic image that detonated the world, these "sinners" walked the most shocking waltz between technical parameters and ethical shackles. When the torrent of large AI models swept the world, they finally understood the function diagrams drawn with coffee stains in each other's experimental notes - it was a love letter spanning two millennia and the Chinese people's own technological romance.
