Su Wan, a senior in Class 2, always gets distracted during self-study classes in midsummer afternoons - not because she is too sleepy, but because Jiang Xu, who is sitting diagonally in front of her, would put her school uniform jacket on the back of the chair, exposing the thin red string on her wrist. It was the safety rope that Su Wan secretly stuffed into him during the summer camp of his freshman year of high school. He wore it for two years without taking it off. On the title page of Su Wan's wrong-question book, there was a line of words that only she understood: "Jiang Xu's red rope, the overdue midsummer." She always felt that this secret love was like an uneaten popsicle in the summer, which should have melted before school started, but instead stayed frozen all spring and autumn.
Purpose: Happy every day
