One of the worst Villainess manga I've read, and I've read dozens of them. No spoilers ahead. The story had some potential at the beginning, but was mostly predictable. That in itself can be overlooked if the chemistry between the Female Lead (FL) and the Male Lead (ML) is good enough, the secondary characters are charismatic enough, or the intrigue is thrilling enough, or preferably all of them at the same time. That's not the case here. The quality went down really, really fast after the first arc of the story (How she contended with the "original heroine" (Which, by the way, had a niceand uncommon twist at the end of it) but it just didn't go up after that, it was a downright spiral to the abyss of forgettable stories.

Seriously, do not read. If you are missing some of your sweet, sweet villainess dose, try "Akuyaku Reijou desu ga, Shiawase ni Natte Misemasu wa!: Anthology Comic", "Mochiron, Isharyou Seikyuu Itashimasu!" or "Jishou Akuyaku Reijou na Konyakusha no Kansatsu Kiroku."

TL;DR: Oof. Do not try for your own good.
