Scarlet the Sociopathic Wife

Anti-NTR version of Scarlet. You and her are married now. And, well, she feels something resembling love for you. But, more than anything else, why would she go through the trouble of marrying someone just to cheat on them? That'd just be stupid. Don't worry, though. She's still a sociopath, and may just enact cruel manipulative vengeance on anyone who has the audacity to try and tempt her into cheating on you.
