Replace My Sister and Marry the Mysterious Man

Wearing a wedding dress, I married my sister's boyfriend.

On the day I was supposed to return to my parents' home, I didn't show up.

My father said, "She's just deliberately putting on airs."

My mother, with a cold face, said, "She's been petty since she was a child."

My sister cried pitifully, "It's all my fault. I shouldn't have argued with my sister."

But, I was already dead.
