A car accident on a rainy night intertwined the fates of healing designer Su Wanwan and Xingtu Group CEO Lu Chengyu for the first time. She stubbornly refused his compensation check, just to protect her sister's legacy that was damaged in the car accident; while he looked on coldly, he discovered in her design draft secret clues from the fire seven years ago - those rounded corners and anti-collision details were surprisingly consistent with her sister Su Niannian's school bus accident report.
Three days later, Su Wanwan joined Xingtu as a specially recruited designer and was forced to take on the challenge of renovating an abandoned factory. Workplace conspiracies ensued: rival Li Man tampered with data, spread rumors, and even stole design drafts. But Lu Chengyu always observed silently, the star-shaped scar on his wrist leading to the past like a puzzle. When Su Wanwan's "Urban Memory Museum" project illuminated the abandoned factory building, behind his decision to increase the budget was a silent recognition of her concept of "using architecture to heal trauma."
A contract marriage binds two people. Lu Chengyu used the shares as bait to find out the cause of his sister's death; Su Wanwan, in order to find the truth, recognized his saving figure in the old photos of the orphanage. During their cohabitation life, he clumsily made coffee and sought medical treatment for her cat late at night; she touched the scar on his wrist, awakening the memory that had been erased by the fire - it turned out that seven years ago, he rushed into the fire to save Nian Nian, but he was left with permanent scars due to a falling beam, and he even forgot his promise due to a car accident.
From workplace confrontation to contractual marriage, from hidden scars to the truth, two broken hearts are stitched together in a healing design. When the pale pink star-shaped birthmark appeared on the wrist of the new life, they finally wrote the ultimate code of two-way redemption in the galaxy of love and architecture.
