After I Die, My Sister Wants to Take over My Husband

My twin sister always says she is a heroine and can get whatever she wants. Later, when she wanted my husband, she gave me a glass of poisonous wine and asked me to be the nourishment for the flower. On the first day when she was pretending to be me, she particularly disliked my clothes because my clothes were all plain. I really have to wear it. She must not know that my husband will end her happiness.
