Nina Xu, a glamorous film director, has just discovered that her scumbag boyfriend cheated on her. Furious and unwilling to back down, she sets her sights on revenge—in the most scandalous way possible. Her plan? Flirt her way into becoming the girlfriend of her ex’s elder cousin, aiming to become the future "sister-in-law" and stomp all over her ex's pride. But things take an unexpected turn when she accidentally sets her sights on the wrong man—none other than her ex’s legendary younger uncle, Gavin Fu, a cold, ascetic doctor with a monk-like reputation in the medical world. Nina Xu immediately panics, but it’s too late. Gavin Fu has already taken notice. With one hand around her slender waist and a chillingly calm voice, he tells her: “You came to me. Now you don’t get to run.”
