It was a villainess story. She was reincarnated with white hair and always coughing up blood. She martied the magician guy and he’s brother is the male lead who’s a tyant. The plot twists was that she did not reincarnate but rather was a sister of the villainess and was swapped. HUHU I FORGOT THE NAME PLS ANYONE
