In "reincarnated as villainess" manga stories, either the original heroin is not reincarnated and became a good friend of the reincarnated villainess , or she is a reincarnation too, become the "villainess" rival, and thus the new antagonist (or a third reincarnation is the male lead, everyone stay nice, and decide "Screw this, I'm out of here" before the plot catch them finally) . In " An Observation Log of My Fiancée Who Calls Herself a Villainess", and "I'm the Villainess, So I'm Taming the Final Boss", it's the second case.
Heronia Inderon (yes, the first syllables literally mean "heroine") and Lilia were, respectively, the original heroines as their pink haired sweeties' appearances indicate it. Problem, Bertia Ibil Noches and Aileen, the original evil rivals in the games these stories are from, are nice girls reincarnations who steal male leads and spotlight. Heronia and Lilia don't take it well, albeit differently.
Heronia panics, enrages, and blindly follows the exact original scenario, not realizing it has changed; while Lilia, probably more intelligent, stays mostly calm and is more prone to manipulation and violence. "Queen of mean" ("Descendants 3") seemed, to me, to fit perfectly both, so I made a good old fashioned AMV.
