She has the power of mind control. It was mentioned that her previous realationships ended because her partners were insecure and doubtful because of her power. They suspected that she controlled their minds to like her. But she never used her power for that short of things. The reason she broke up with the duke was because she was afraid that the duke would also react to her mind control power like other people

They didn't elaborate on the powers much. Like the oldest sister has supernatural strength and the 2nd sister has mind control power, idk about the 3rd sister tho. Maybe her's wasn't mentioned.Their powers aren't shown much in the manhwa. I would like to know more about the powers and each sister individually cause they are so interesting and I just love the sisters bonding SM. (=・ω・=)
SHE CAN READ MINDS???
then again I need to re read this manhwa from the very beginning since I forgot major details
