Born without magic, Saphiras has always been treated coldly by his family. One day at the aristocratic academy, he is nearly assaulted by his scummy fiancé. In a desperate attempt to escape, he jumps from a second-story window and regains the memories of his past life as a legendary sorcerer. With this, he decides to embrace a new life. However, the people around him continue to keep their distance. Amid all this, Percival, a top student with the air of a knight, approaches him without hesitation. As their friendship begins to grow, a chaotic academy life unfolds, where Percival wants to protect him while Saphiras insists on solving things by himself.
