This is a story about two people with completely opposite personalities falling in love. Jiang Yan, a science student, is both brilliant and aloof, earning him the nickname “Iceberg Genius.” Su Muchen, a humanities student, is warm and outgoing, and a star debater. The two can’t stand each other in high school and bicker every day. A few years after graduation, they finally get together, ready to spend their lives side by side.
In a September classroom steeped in twilight, the scratch of pens across exam papers gives way to a clash of reason and emotion that catches like wildfire. Clutching her essay, she argues her case with burning conviction. He adjusts his glasses and calmly breaks down the issue, his logic sharp as a blade. Their argument over grading criteria begins as a dispute, but becomes the silver needle with which fate stitches their lives together. Forced by fate to share a desk, they quietly weave an understanding amid the drifting chalk dust.
Whenever she dozes with her head on her arms, he sorts her math mistakes carefully by problem type, his flowing ink strokes as upright as pine trees, an unspoken tenderness hidden in every line. When he turns away to practice piano, she draws a lively little sun on the back of his guitar. Her bright yellow strokes seem to shine right through the wood, lighting up the whole room. The sweet steam of tea from the milk tea shop on the corner, the silver light spilling across the library floor through its tall windows: these fragments of time come together to form the secret language of youth that belongs only to them, glowing brightly through the years. From “a clash for the top spot” to “together for the rest of our lives,” Jiang Yan’s quiet devotion and Su Muchen’s passionate, direct affection nourish each other. The little sun and the little guitar remain recurring symbols throughout, telling a love story that grows from school uniforms to wedding dresses and exploring the theme of growing together while staying true to oneself.
