Su Wan is a "little transparent" top student in the Department of Chinese Language and Literature. Her biggest hobby is to sit by the window in the library and write essays. Until one day, Lu Xingyan, the school boss of the Computer Science Department, suddenly sat across from her and handed over a note: "Classmate, can I borrow a pen?"
From that day on, the aloof school sweetheart became Su Wan's "fixed self-study partner." He would help her secure a seat by the window in advance, bring her warm strawberry milk (remembering her preferences), and help her sort it out in a logical and clear way when she was stumped by the translation of ancient Chinese. Su Wan would also bring Lu Xingyan a warm breakfast after he stayed up late doing experiments, and would hand him a strawberry candy when he was irritable writing code. He would also listen carefully to what he said about computer knowledge that he did not understand.
At first, Su Wan thought it was just "learning to help each other", until Lu Xingyan grabbed her hand when the power went out in the library, used the code to make an exclusive electronic poetry collection for her on her birthday, and rushed to her and hugged her immediately after winning the basketball game. Only belatedly, she discovered that love had already quietly sprouted on the paper scratched by the pen tip, in the aroma of coffee and milk.
