I Will Not Be an Enemy!

From an early age, Kiara has been plagued with dreams of another world—dreams in which a girl she doesn't recognize plays a strategy RPG called "Farzia: Kingdom at War." Farzia is, in fact, the same kingdom where Kiara currently lives. Oh, and one other thing: there's an enemy character who shares her name, though her name is Kiara Credias. Naturally, as with any other RPG villain, this enemy is destined to be slain by the heroes. When her adoptive father, Count Patriciél, orders her to marry Viscount Credias, Kiara comes to a horrifying realization: perhaps those "dreams" were visions of things to come! Now faced with a fate she desperately wants to avoid, she must find a way to change her destiny and forge a new path for herself in a world where the lines between game and reality have begun to blur.
