What the story promises: a meta-villainess romance with a twist
Genius crown prince Cecil is engaged to Bertia, a duke’s daughter who insists she’s the “villainess” from a past-life otome game. She keeps staging “evil” set-pieces to force a breakup, but her plans backfire thanks to her kind heart—and there’s a reason she must be “defeated.”
