Regolith, a Japanese interior decoration brand that has been gaining momentum in recent years, has begun to expand its overseas market and has chosen Shanghai as its first overseas branch. Because of its entry, a factory closed down, causing strong dissatisfaction among workers including Liu Xiumei (played by Lin Chiling), which in turn triggered a large-scale sit-in. Regolith's boss Ye Yue Renjie (played by Kimura Takuya), who came to inspect, saw this scene. Renjie, who has a strong personality and wants to do everything to the end, tried every means to calm the incident. So Renjie commissioned his assistant Cai Fengjian (played by Matsuda Shota) to investigate Xiumei's background and asked Xiumei to be the spokesperson model for his brand. Under Renjie's transformation, Xiumei became a brand new, and Xiumei also went from disgust to liking Renjie in her contact with him. After the sit-in incident was calmed down, Xiumei went to Japan with Renjie. Rensuke has not only Hidemi, but also his long-time friend, the company's designer Ninomiya Maemi (played by Shinohara Ryoko) and his rumored girlfriend, the popular model Onuki Yuzuki (played by Kitagawa Keiko). How will the three women choose? Can Rensuke, who is strong and unpopular, keep the company running normally? At the same time, conspiracy and betrayal are also breeding behind the scenes...
