The Rise of the Duke's Son

I was in a long deep sleep when I opened my eyes, I was inside an otome game called [The Noble Lovers]. [The Noble Lovers] is an otome game focused on the adventure of the heroine, Emily Claes, an eighteenth years old commoner who is accepted into a noble school full of magics and swordmanships because of her rare white magic or what some other people called as pure magic and her path to conquer the hearts of the male leads and to beat all of the love rivals and the villain of the game. Unfortunately I become part of the novel as the useless trash son of the Duke's family, who is the strongest family in the whole kingdom of Redvelve Kingdom. But the real problem is that the useless trash son of the Duke, Algard Sora Halford, is a whole idiot and a jerk who always messes and tried to harass the heroine, only getting beaten up and getting killed off by the male leads in the ending of the game. ".....This is going to be such a drag...." But look at the bright side if this is really my second chance to redeem myself in this second life then I might change the game ending and live the best day of my life in this life.
