“It's commonly believed that I'm arrogant and aggressive. Let's teach them what arrogance really is! Anyone who dares to provoke me is doomed!”

Formerly a professional bodyguard in the modern era, Xue Moyun dies while on the clock. When she wakes up, she finds she's inhabited the body of the Prime Minister's eldest daughter, a long long time ago. And as it turns out, this girl has just had two engagements annulled one right after the other—one to the crown prince, and then one to his younger brother after that! What's an arrogant girl to do?!
