I was Reborn as the Villainess but I will become a Great Sage

Nova Allandis, formerly known as Suna Lee, remembers her previous life and realizes her current life is as the villainess in a fantasy novel she once read. However, as Suna, she was the laziest person with no motivation, possibly attributed to the fact that she didn't go into a major that was her strongest suit. Now that she has a high affinity towards magic and wishes to go into it, will she be able to change her lazy self for the better, or will she go back to being lazy like the villainess in the novel? Can she become a Great Sage and live life happily this time? Note: This is not a "revenge of the villainess" novel, but rather a "rise to fame" novel.   A/N: This is just an experimental novel and criticisms are much appreciated, but I'm extremely defensive of my own work and characters. If you are here to put down a novel, please remember, first of all, you are not paying anything to read this, and second of all, authors are humans too.
