She Has A Crazy Streak

In her past life, she was betrayed by her scumbag husband and her sister, thrown into a mental institution, and tormented to death. But when she opened her eyes once more, she had been reborn… right before she had gotten married to her backstabbing husband. This time, she's not letting them off easily. Didn’t they call her crazy? Very well then. She would show them just how crazy she can be and make them regret ever crossing her!
