I was forced to marry a man who hates me. Which is to be expected since my mother killed his family.
“I want you to promise me before we get married. After 6 months of marriage, I want you to divorce me.”
“What?”
“I know you were forced to marry me. We don’t need to draw out an unwanted marriage, do we?”
“An… unwanted marriage?” He dazedly kept on repeating my words.
