Lin Xin'er’s girlish feelings were hidden in the gaps between the years of her youth. Ever since college, she had secretly loved Li Yunze, the son of her aunt’s best friend. With his wild, carefree exterior and sunny, handsome looks, he was the brightest light in her youth.
In their graduation year, Lin Xin'er finally worked up the courage to slip a confession letter into Li Yunze’s schoolbag, hoping with all her heart that he would respond. But fate played a trick on her. Li Yunze’s close friend Wang Yi borrowed the schoolbag, and the letter carrying her feelings sank without a trace, never reaching Li Yunze. During a graduation trip, Lin Xin'er happened to overhear Li Yunze and Wang Yi talking and mistakenly thought her crush was unrequited. The pain of heartbreak swept over her like a tide, and from then on, she cut off contact with Li Yunze.
Time flew by. Lin Xin'er graduated and returned to her hometown, where she successfully landed a job. By then, Li Yunze had inherited his family business and taken over its KTVs, pool halls, and other ventures, making a name for himself in the business world. By chance, Lin Xin'er went to sing with her coworkers at the biggest KTV in town, which happened to belong to Li Yunze. When a familiar figure appeared before her, memories she had buried came flooding back. After years apart, their eyes met, and the air seemed to fill with a different kind of feeling. Could the fate they once missed begin anew in this moment? Would the two of them spark a romance and continue the story they had left unfinished?
