At the end of summer, when the wind blows in the parasol trees, Lin Wan, a girl who is slow to learn Chinese and is soft-spoken, meets Jiang Yu, a cool and taciturn student in the computer science department, in an elective class. When we first met, he was distant, cold and unapproachable. After getting along with each other, I slowly discovered that this iceberg hides the most delicate tenderness. The window seat in the library is always reserved for her, the umbrella that is tilted half way towards her on rainy days, the company that deliberately takes detours under the street lights during evening self-study, he will patiently explain difficult problems and endless homework. He keeps a distance from everyone, is cold and indifferent, and keeps away from strangers. Only towards her, he was soft-hearted, accommodating, worried about everything, and silently told the truth. We meet by chance again and again, and we quietly care about each other again and again. The glances at each other in the corner of the eye, the inadvertent touches, the cheers from friends, the hidden heartbeats. A cautious two-way secret love slowly ferments in the autumn evening breeze. From being a stranger at the same table in elective courses, to studying side by side every day, from being young and heartbroken, to seriously confessing to each other in the evening breeze. There are no bloody misunderstandings, no sadomasochism, only clean and pure campus time, and tenderness that goes both ways. We spent the finals week together, watched the sunset on the playground, and walked through the Four Seasons campus. In the ordinary university, we meet each other, heal each other, and shine together.
