The Beginning of Revenge Starts with Marriage

My father had an affair with the Empress.
I could endure that.
At least until my sickly mother found out the truth… and until Father and the Empress began threatening her one after another.
“I never thought she’d suddenly die. Your mother turned out to be such a fragile woman.”
Before my mother’s cold body, the man I had to call Father spoke shamelessly.
“I hope you don’t hate me too much for your parents’ issues. After all, we’re about to become family, aren’t we?”
The Empress, who wanted to take me as her daughter-in-law, smiled as she spoke about creating a happy family.
They’re all insane.
And for madmen, the only fitting answer is a vengeance just as mad.
“Please, marry me, Your Imperial Highness the Crown Prince.”
This was the day before my marriage to the Empress’s son.
