Hazuki Rensuke is the president of Regolith, a design company quickly rising to the top. Wishing to expand, he buys a factory in Shanghai, where Xiu Mei, a poor worker taking care of her sick mother, is employed. On the news of the purchase, the workers begin protesting. In the hopes of ending the protest, Rensuke makes Xiu Mei the model of the company. Trusting Rensuke to keep his promise of keeping the workers employed, Xiu Mei travels to Japan where she becomes close friends with Ninomiya Maemi. Upon discovering that Rensuke has fired everyone, Xiu Mei vows to capture and break Rensuke's heart as revenge. Meanwhile, Oonuki Yuzuki, the daughter of a rival company and a model, and Maemi are both in love with Rensuke, too. Rounding off the cast is Sai Kazami, Rensuke's right hand man who has his own agenda.
