On the day she had a falling out with her unscrupulous ex, Mu Xia found herself a pretty older sister. At the time, she thought the woman was just an ordinary person with a rough past—so she had fun and left without a second thought. Days later, Mu Xia went to present her proposal to the client. When the poised, elegant, and all-too-familiar young boss walked in, her world shattered... No wonder the woman had repeatedly warned her that night, "Mu Xia, don’t mess with me." Turns out, she really was out of her league. A rookie facing an industry titan—she never stood a chance. Yet in that one wild night, she’d left bruises on the woman’s wrists. The more their lives intertwined, the more Mu Xia realized: this woman was trouble. And she finally understood—getting involved with someone she shouldn’t wasn’t due to her youthful charm or sweet smile. It was because that woman had been lying in wait, ready to devour her all along.
