A fire seven years ago shrouded the lives of Shen Zhiyi and Lin Yanzhou like a thick fog. The gears of fate turned sharply, and the two were separated in the light of the fire, each carrying pain and secrets as they moved forward.
Seven years later, they unexpectedly reunited in the "Jiuyu Bookstore" that was filled with the atmosphere of old times. The once youthful boy has grown into a calm man, while the weak girl has also learned to be strong through hardships. But the haze of the past has not dissipated, and Li Zheming's resentment has always followed, becoming a thorn between the two.
In every corner of the bookstore, memories come flooding back. Paper cranes and maple leaf specimens, these old objects carrying the past, connect their youth together. Lin Yanzhou guarded her silently, trying to make up for her past regrets; although Shen Zhiyi was moved in her heart, she was also hesitant because of the pain of the past.
Between misunderstanding and reconciliation, can they break through the obstacles, turn the echoes in the fog into affectionate confessions, and regain the sincerity interrupted by fate...
Concept: Lin Yanzhou accompanies Shen Zhiyi, and the bonds of the past finally blossom into deep affection.
