Yun Shu transferred to Qinghe Middle School in the summer when cicadas were singing. The red line of fate caused her to accidentally collide with Lu Huai on the campus path, starting a heart-pounding story.
When they first met, Lu Huai's gentle help was like warm sunshine shining into Yun Shu's uneasy new campus life. As they get along more and more, the two develop a secret affection for each other, leaving their warm footprints and sweet memories in every corner of the campus.
The preparations for the campus cultural festival provided an opportunity for their relationship to heat up. Yun Shu enthusiastically signed up for the calligraphy exhibition, and Lu Huai gave her full support, looking for precious copybooks and accompanying her to practice. However, twists and turns came one after another. Yun Shu's beloved writing brush was lost, and the works at the cultural festival were accidentally destroyed. However, with Lu Huai's constant encouragement and company, Yun Shu faced it bravely. With perseverance and talent, he shined in the calligraphy exhibition and won the first prize.
On the stage of youth, Yun Shu and Lu Huai support each other and grow together. Their love blossomed quietly in the breeze, warm sunshine and fragrance of books on campus, interpreting a romantic chapter of two-way secret love and sweet doting.
