A girl who was originally only attracted to men caught her boyfriend cheating on her with her stepsister on the wedding night when her mother married into a wealthy family, only to be falsely accused of a pregnancy scandal in return. Everyone at the scene demanded that she keep quiet, but only her stepfather's sister — handsome, dangerous, and so domineering that it bordered on possessive — pulled her away from the humiliating scene, forced her to learn to fight back by the rules, and forced her to admit that she had fallen in love with a woman.
