Captured by My Fiancé’s Brother（DUBBED）

Go Su-hyeon arrives in the capital determined to avenge her mother, using her engagement to the commander-in-chief's second son as cover for her real purpose. Her plans take an unexpected turn when she meets Han Ju-won, her fiancé's older brother, who keeps pursuing her even though he knows exactly who she is. Each move she makes toward revenge pulls her closer to his hold on her. His only warning to her is simple and stern: she must not run, because she belongs to him.
