Tensei shita Akuyaku Reijou wa Fukushuu wo Nozomanai

A second chance at peace...or revenge?! After being hanged for a crime she didn't commit, Rosemary entered the annals of history as a villainess. So when she reincarnates as Mary with her memories intact, all she desires is a peaceful existence. And yet she's forced back into the world of politics against her wishes! "Now then, dear sister, how would you like to punish those who killed you?" Mary's brother—who she loved so much in her past life—has undergone a terrible transformation. Now, he seeks revenge on her behalf. "Tell me what you desire, my lady." Likewise, the knight who swore allegiance to Mary in her past life makes the same vow in the present. Despite all this, Mary doesn't want vengeance against those who killed her. But will the people surrounding her allow for peace? (Source: Cross Infinite World)
