Captured by My Fiancé’s Brother

Go Su-hyeon comes up to the capital as the promised bride of Han In-ho, the second son of the commander-in-chief. The engagement is cover. Her mother was killed and the man who did it is in the capital, and that is the reason she made the trip. She meets Han Ju-won, the eldest son of the same house, on the train. He works out that she is engaged to his younger brother and comes after her anyway. "Don't run. You're mine," he tells her. Su-hyeon holds him off and starts using the medical skill she has kept hidden for years, treating people in the household to earn their trust and working from inside the house toward whoever killed her mother. Ju-won does not let go of her, and somewhere in it she stops being sure that the revenge is what she wants most.
