As a Result of Settling the Climax of the Broken Engagement First

"I hereby break off our engagement with you!" It was at a banquet announcing their engagement that Prince Eric declared the breaking of his engagement to Lucia Sanshīru, the Duke's daughter. Since they had planned to proceed with the formal engagement procedures after announcing their engagement, the two were not yet officially engaged. Upon being declared the breaking of the engagement, Lucia pumped her fist in victory in her heart. (I've already taken care of the climax.) Lucia was a reincarnator, and this world was the world of an otome game.
