A high-ranking mage of unknown identity had blown her to bits, and the people of Pulaici celebrated for three days and three nights. The good news was that not a hair remained after the explosion. The bad news was... she had been reborn. - “You vile daughter of a lowly washerwoman!” “A disgrace to the royal family, with filthy commoner blood!” “Disgusting dark mage!” … In her previous life, Wenda Ya had been saddled with too many labels. Given another chance, she found herself in the body of Daya, the Second Princess of the Koyiqielin Empire. She lifted her eyes and smiled faintly, hiding a knife behind her back. She had meant to quietly scrape through four years at the Lorenzo Academy of Magic, but accidentally became the center of everyone's attention. Even the man who had cheated on her with her sister fell at her feet again. “Princess Daya, I refuse to cancel our engagement!” Wenda Ya watched a certain professor's lips draw into a tight line and deliberately replied with a troubled air, “Really? I have no say in our engagement either, so then the engagement...” “Is canceled. I decide.” [Wild Rose Empire princess X magic academy professor] “Wenda Ya, you are my only reason for remaining in this world.”
