I wouldn't be surprised if the heroine said something to him which caused him to send hit-men on her. I've seen it happen in other villainess stories. RandilC
Ugh, those innocent looking heroines that end up being the actual villain yeah... Well I wouldn't be surprised since mc became her friend instead of bullying her and she still went for the prince without telling her anything (〜 ̄△ ̄)〜
Also wtf is the deal with that prince trying to kill her after breaking their engagement
