I was reincarnated into an otome game, but I think it's completely a case of mistaken identity.

I was reincarnated as the protagonist of an otome game, but I'm male in my previous life. If my older sister or younger sister were to be heroines, that would be one thing, but I'm not pleased about it at all. I'll enjoy my studies, training, and romance without worrying about heroines! But why is there an engagement cancellation scandal? And on top of that, I'm the villainess!? This is no joke! Help me! Evil Lady!
