In the key high school "Xingze Middle School", Su Nian, a master-level transfer student (cold on the outside but soft on the inside, hiding his talent for painting) and Lu Xingyan, the school basketball captain (sunny and naughty, a student with special difficulties in mathematics) accidentally took each other's books in the library because of a bookmarked "The Little Prince" with a cherry blossom bookmark, and started a "misplaced interaction".
