Architectural designer Cheng Xi once firmly believed that "drawings can outline all the light." However, at the peak of his career, he encountered design plagiarism and the betrayal of his mentor. He fell from a rising star in the industry to a target of public criticism overnight. Unemployment, debt, and the collapse of trust wrapped around his body like thorns. He hid in his old studio in the old city and almost extinguished hope among the abandoned design drawings. It wasn't until I accidentally discovered the diary left behind by my mentor that I realized that there was an unfinished dream of public welfare construction hidden behind the truth. From then on, he started over with incomplete drawings and scars all over his body. Amidst the lack of funds and pressure from his peers, he gradually implemented his ideal of "building bare-roofed classrooms for rural children". Those rejected plans, torn sketches, and worn leather shoes eventually turned into the starlight in his palm - just like his name, even if he walks through the deepest night, he will eventually wait for the bright light in the east.
