Lin Wan, a professional, returns to her hometown to save the nearly bankrupt intangible cultural heritage fireworks factory by organizing a fireworks festival. There, she unexpectedly runs into Chen Mo—her first love who stood her up on a fireworks night ten years ago and then vanished. To her surprise, Chen Mo is the top fireworks designer hired by the factory. The old misunderstanding is a thorn in her heart, making her defensive against Chen Mo’s approach. But Chen Mo hides a secret: ten years ago, he left to save Lin Wan’s father, who had a sudden serious illness, and chose to remain silent to avoid burdening her. As they work together to resolve the factory’s crisis, they grapple with their lingering feelings and the unresolved past. When the penultimate fireworks light up the sky, Lin Wan discovers the unsent love letter she wrote years ago in Chen Mo’s old belongings. Before the final fireworks rise, Chen Mo finally reveals the truth. Will they let go of the past and keep their “fireworks promise” once again as the sky bursts into color?
