For an Elegant Night of Villains

When I woke up, my seven-years worth of memories was gone.
I was a princess, then became the Grand Duchess,
And was in a hostile relationship with the ‘husband’ who married me four years ago.
And last night, which I don’t remember,
Was my first night with him.
“I waited for four years, and on the next day, you lost your memory. You are truly an amazing woman, aren’t you?”
I think I made a huge mistake.
So in frustration, she tries to search for her memories.
However, when the truth reveals itself to her bit by bit, the reality of the situation was very different from what she previously knew……
After losing my memory, will I fall in love with you?
Wouldn’t you want to let go of someone who knows nothing?
