Lady Regina, the oldest daughter of the Viscount of Fremont, is very protective when it came to her youngest sister, Lily. There're only the two of them against the world. But when a powerful scandal sends her away from England, threaten to dragged down Lily as well, Regina could do nothing except fled to Paris. She came back five years later only to find her sister gone, committed suicide because of her broken heart. Regina vowed to make the scoundrel who caused her sister's life pay and she knew exactly who that rake is. A life for a life. So it's only fair that he paid with his life as well. Regina is not self-destructed to be murdering Lord Robin Locksley, the Duke of Sherwood in London's daylight. Oh no, her plan is much more complex. She'd make him falls in love with her. She'd make him go crazy for her. Then she'll leave him like he did her sister. And even if she'll have to marry the man to have her revenge, so be it!
