I have memories of my previous life. Memories of when I was a Japanese who lived as "I" and was addicted to otome games. Deanna, the villainess daughter who was condemned by the prince at her graduation party and sent to a brothel after being expelled from the commoners. She has memories of her previous life, so she can see such a development. Before she was convicted, she bought a brothel and became its owner. She accepts her banishment without hesitation, and while she is secretly trying to enjoy a leisurely life at the brothel where she was banished, Alexis, who is close to the prince, comes after her... Is he an enemy or an ally? From "Let's become a novelist", the retaliation of the exiled villainess who is not easy to deal with begins now!
