A Fanfic of 'Madam, Your Secret Identity Is Showing Again': An Accident at the Auction

Any Stories with Two Equally Powerful Leads, Like Who Rules the World?

Two equally strong leads, historical romance. The male lead should be calculating, scheming, and tsundere; the female lead should be bold and forthright. They should both have secret identities. The character dynamics in "Try the World" absolutely kill me!!
