Set against the backdrop of massive economic growth in the 1990s, the story follows A Bao, a self-made millionaire and his journey from being a young opportunist with a troubled past to accumulating dazzling wealth in the city of Shanghai. It also follows his entanglement with four women who represent the pursuits of his life: adventure, honour, love and innocence.
In school, Wang Hsiao-hsia and her childhood friend Yuzu are seen as a couple, but Hsiao-hsia secretly longs for the transfer student Cheng Yih. Cheng Yih, admired for his exceptional grades, talent, and fighting skills, captivates her heart. Despite her poor academic performance, Hsiao-hsia tries various methods to win his affection, but nothing works. Unbeknownst to her, Cheng Yih harbors feelings for Hsiao-hsia as well. Meanwhile, Yuzu, fiercely protective of Hsiao-hsia, is wary of anyone trying to get close to her. As summer arrives, a fragrant first love begins to bloom among the three of them, reminiscent of lemongrass.
