Four decades ago, four beautiful little girls (Yu Na etc.) share a happy primary school life in a legendary children's art troupe class named Little Red Flowers. The class president, Lu Si Yuan, is their common idol, which leads to two love stories of him with two of the girls when they grow up, yet both end in sadness. The novel tells the touching stories of the four girls' different paths of life ( a dancer-turned official, a film star-turned business woman, an overseas-returned scientist, and a successful entrepreneur), which are colorful but also hard.
