ML! I AM NOT YOUR WIFE

I woke up in a novel.
i become the cannon fodder ex-wife of the ML who was hopelessly in love with him.
The character was supposed to die but now i am in her body.
LOVE! I am gonna get a divorce anyway it was a contractual marriage.
MONEY! As a genius hacker money is nothing to me.
MEN! Well they flock around me because of my beauty.
But what is this? A man keeps pestering me.
Finally i lashed out,"Who are you?" He said,"My dear wife have you forgotten about me?"
