Qi Yue, a 26-year-old architectural conservation designer, is as stubborn as the old walls she repaired.
The Qingshi Lane century-old street renovation project was an opportunity she had waited for three years for. She vowed to make these old houses "live with dignity." But the new investor representative turned out to be the senior Lu Chen, whom he had a crush on in college - the boy who once said he wanted to "fix time" has now become a cold-blooded developer who "prioritizes functionality".
Their ideas are like two opposing old buildings: she wants to restore the old and keep it the same, and he wants to demolish the old and build a new one. Every confrontation is tearing open old wounds from seven years ago - that unattended date on the rooftop, that half-written confession note, those youth buried by misunderstandings and family pressure.
When the conspiracy surfaced, when the old craftsman's notes were revealed, and when the century-old underground palace unexpectedly appeared, Qi Yue discovered that Lu Chen's indifference was nothing but armor, and what they both wanted to repair together was not only Bluestone Alley, but also their own lives that were riddled with holes.
This is a battle about persistence and compromise, ideals and reality, love and redemption. In the cracks of time, they finally learned that good repair is not to cover up the scars, but to make every mark live with dignity.
