Thirty-two-year-old architectural designer Wang Bulan accidentally reunited with his first love Lin Chujing who broke up eight years ago when he was in charge of an old city renovation project. At this time she is a cultural heritage protector and he is a representative of developers who want to demolish old buildings. Opposing positions and flooding memories, I thought it was just an accidental confrontation in the adult world, but I didn't know that hidden under the mottled walls of the old theater was a secret that would change everything.
As the project progressed, they discovered that their breakup was not as simple as it seemed - their mother's well-intentioned intervention, unsent letters, a time capsule hidden under the seat, and a night that changed the trajectory of their fate but no one knew it. In the gap between the collapse of old walls and the rise of new buildings, between the struggle between career crisis and persistence of ideals, two people who once thought they had let go of the past had to re-examine: some flames seem to be extinguished, but in fact they are just waiting for oxygen.
This is not a simple reunion, but two adults, carrying the weight and scars of their own lives, learning to love each other again on the ruins of reality - more soberly and bravely.
