Past Life Countess, Present Life Otome Game NPC?!

Oh dear, it seems I was reincarnated into a modern otome game from a fantasy world!

All I ever wanted was to be free of my responsibilities as a countess and I finally got my wish when I was reborn as a commoner in modern Japan. Everything was going perfect, except it turns out this is the world of an otome game and some crazy girl who goes around calling herself the “heroine” is upset at me for stealing all her “events” with the “love interests”… Now she wants me to team up with her against the “villainess”. I’m supposedly just a random NPC, so why am I being dragged into this?!
