Blue Butterfly Message in the Window

In the summer of her sophomore year in high school, Lin Wanying transferred to No. 1 Middle School and became Shen Zhixia's new deskmate. She always likes to stare at the wind outside the window in a daze, and there are pages full of blue butterflies hidden in the picture book; he is always the first in the grade, always cold, but when she is trapped by a problem, he will calmly push the written steps to solve the problem in front of her. Only later did she discover that those blue butterflies lingering on her window sill, those identical butterfly-shaped graffiti on the draft paper, and those unknown tenderness, turned out to be the heartbeat that he had hidden throughout his youth. It turned out that the midsummer wind had already written his secrets into every butterfly in her window.
