A story about pushing everything onto my younger sister and running away with my lover from my past life who is a villainess.

I am an adult woman who was raised as a Japanese person in my previous life! Before I knew it, I was reborn as a baby in another world—what a disaster! Just when I thought I could grow up without incident, my twin sister who hit her head starts saying this is the world of an otome game, making things even worse! This is such a tired trope! Huh, a villainess? Could you possibly be the woman who was my lover in my previous life? If so, why don't we leave this role to my sister and run away together?
