There's No Such Thing as a Villainess Route? Not in My Book!

Story:

I reincarnated into the world of an otome game as the villainess, “Ophelia.” I thought I'd be able to enjoy a peaceful school life, but to my dismay, I found myself subjected to constant harassment at the hands of the wicked, vindictive heroine; and to top it all off, I’m plunging headlong into the dreaded Bad Ending — hold up, as if I’d meekly submit to such a fate! If that’s how it’s going to be, I’ll tap into the top secret "cheats" known only to those who've played the game and carve out the 'Villainess Route' of my fantasies!! But for some unfathomable reason, the capture targets seem to be doting on me far more aggressively than in the original story…?
