I Reincarnated as a Hidden Villainous in High Society

Getting sick during a particularly cold winter night, I "Liana Briar" remembered my previous life. Or rather, bits and pieces of it anyway... In those bits and pieces, I vaguely recalled the novel series "Catina's Secret." Rated "M (Mature)" Despite starting in a high school setting due to the steamy scenes between the 'heroine' Catina Rose and each of the male leads (and no there was no reverse harem option).
And as the cliche goes depending on which male lead the heroine chose, a 'hidden villainess' would naturally appear to hinder the heroine.
As it turns out Liana Briar was one such hidden villainess. However cliche it might be, I have no intention to live my life according to a novel.
