When the Dream of Becoming an Immortal Becomes a Reality

(Chronology) the Female Protagonist Is Selfish and Just Wants to Take Advantage of the Male Protagonist Not Loving Him

I want to read a book like "The Gentle Handicapped Man Is Actually a Yandere and Paranoid Man". The female protagonist just wants to use the male protagonist to live a good life, but she finds that the male protagonist is paranoid and uncontrollable. She wants to escape from the male protagonist but cannot escape.
