Gu Ke-Wen

She collaborated with Lin Bo-Wen and his sister Lin Ya-Ru to cheat Liu Ying out of her shares in Nice Moves Sports Equipment in an attempt to steal the idea of an automated surfboard only to find out that Xia Lei had secretly contacted Long Bing and already had the patent for it. She then threatened Liu Ying into giving her the pattern before using Huang Yihu to get revenge against Xia Lei. After the Gu clan's downfall she tries to convince Xia Lei to help her fight against Qiu Jia, going so far as to offer her body to him, only to be rebuffed. She then leaves and is kidnapped and trained by the CIA, appearing later as an assistant to Shentu Tianyin where she gets her to buy up quasi-legal Gu clan assets and encourages the relationship between Xia Lei and Shentu Tianyin. After the pair become married, the CIA then kidnap Shentu Tianyin and force Xia Lei to save her but they eventually fail. Gu Ke-Wen then blackmails Xia Lei into releasing her brother Gu Ke-Wu from jail and bringing him to Japan in return for not revealing Shentu Tianyin's acquisition of dirty Gu clan assets.

You know that the Gu clan is one of the most powerful families in Jing-Du, right? The Gu clan controls North Group, which is worth billions and has a wide reach. What you don’t know is that the Gu clan actually started here in Hai-Zhu. Gu Ke-Wen’s grandfather, Gu Ding-Shan is actually a figure in the underworld too. Nothing in the Gu clan’s coffers is clean. The Gu clan has always been vicious. Anyone who goes up against them would have a bad end.
