In the midsummer of that year, the last row of Class 1, Grade 3, became the most mysterious scenery in the school.
On one side is Lin Wan, an illustration girl who is always out of the situation but as warm as a little sun.
On the other side is Jiang Yan, the competitive academic god who is always in the state but as alienated as a polar iceberg.
Everyone thought that their worlds would never intersect, until one day, Lin Wan's orange-scented watercolor accidentally stained Jiang Yan's spotless white shirt.
This is a story about secret love, growth and two-way running. When the orange-flavored breeze hits the ice-cold soda, sweet bubbles begin to bubble throughout the summer.
