I have the POWER to punish evil but I WANT to be evil?

The protagonist died suddenly in her past life. Entering the book she had read, she does not know what awaits her. Our character's personality is very strange. She is a crazy and cruel woman, but at the same time a tragic one. The further she goes on her adventure, the more hidden things about herself will come to light. The curse that was on her was causing her to gradually lose the ability to have feelings, and her only hope to feel them again is love. Too bad she only has one chance and fate was so bad for her... So her love story became more of a tragedy where her unstable mind was trying to stay whole... Too bad these happened too suddenly .... Just when she was ready to destroy the planet and all the people on it, a certain someone saves them by turning everything upside down for her. Now there is a long fight for the two of them, but strangely the girl's body suddenly gave way. When she opens her eyes again she is in another girl. It's just that not only the body has changed, but also the soul... Now she has put together all the missing pieces of the puzzle of her past lives and a shocking truth has come out that is not only shaking her but the whole world... Now the real story will begin... The author here: the first volume is more like ...hmm... chapter zero? Introduction ? The beginning? The real story will actually begin with the next volume. The first flight is called the 'Origins Scenario' and has a much deeper meaning. It will probably have more than 100 chapters so there is still a long way to go before we can talk about the next volume... I hope you like my book :)
