I Was Reincarnated as the Heroine on the Verge of a Bad Ending, and I'm Determined to Fall in Love!

One day, office worker Suzune (Reine) is reborn as Raine, the heroine of a "work-based otome game" that is too far away from romance. She wants to fall in love with a handsome man in this life! However, she finds herself in a world where there is a magical caste system, and to her surprise, she is the lowest rank! Her family treats her coldly and she is on the verge of being expelled from school... Even so, she is undeterred by the "strong mentality" she has developed in her previous life. Practising magic, studying, and increasing the likability of her targets, she runs hard to avoid a bad end and get a sparkling school life! As Rene pushes forward with such a bright and positive attitude, her high-spec brother Julius, with whom she was supposed to be on bad terms, somehow begins to dote on her - or does he?
