[Substitute + Brother-in-law Literature + Marriage First, Love Later + Contractual Engagement]
On the day my sister fell from the building, she sent me the last message:
"If I die, marry him for me. Don't believe anything he says."
I put on my sister's white dress and married the man who made women all over the city go crazy.
On the wedding night, he pinched my chin with cold eyes:
"Who are you anyway?"
I thought I was just a substitute for my sister.
Until I turned to her diary, and there was blood-stained writing on the last page:
"He knows my plan. He's coming."
I discovered that my sister was my substitute from the very beginning.
And I have already walked into the death script he laid out for us sisters.
