The book 'Time With You' might meet the requirements. The male protagonist, Lu Xi, had secretly liked the class monitor in high school, but his confession was rejected many times. Later on, the two of them stopped contacting each other. When it was time for the blind date, the two of them reunited again. The past reappeared, and the male lead, Lu Xi, confessed to the class monitor again. I hope you like my recommendation. Muah ~
