When the sycamore leaves were falling in late autumn, jewelry designer Su Qing reunited in a cafe with her ex-boyfriend Lin Shen, who had disappeared for five years. He was wearing a suit and ties, still as calm as a mountain, but her fingertips were trembling and her throat was sore. There was no news from him after he left a brief breakup letter, and the questioning letter on the rainy night has not yet been sent; he treasures her hand-drawn birthday card, and the phrase "Our love is like stars, never fades" on the back has long been wrinkled by tears. The gears of fate are turning quietly - Su Qing received a special wedding ring order: "A broken mirror can be reunited", which requires embedding gold threads in the cracks to make the broken mirror shine again. In the days when he was forced to cooperate with Lin Shen in designing, old feelings surged like an undercurrent, and workplace conspiracy loomed like a dark cloud. When the truth finally peeled away the layers of fog, it was revealed that he suddenly left to take care of his critically ill mother, and her unsent letter hid the deep love they had missed. The two stood side by side in the crisis, only to discover that the rift was not the end, but the starting point of new life. The gold thread on the wedding ring design draft is entangled with cracks, just like they used understanding and courage to melt the broken past into an eternal vow. On the night of reunion under the starry sky, Lin Shen finally said: "This time, I will not let go of your hand again." Can those heart knots corroded by time shine as bright as ever in each other's gaze?
A fate cut off by misunderstanding, a love reborn in the cracks. When the unsent letters and treasured greeting cards reveal the truth, the broken mirror will eventually reflect a tougher tenderness.
