The Transformation of the Villain's Apprentice

The heroine, who travels through the book to become a supporting character, encounters the reborn male villain's second apprentice. In order to avoid repeating the tragic ending of the cannon fodder master in the book, the heroine said in tears that she must educate her apprentice who is still a little puppy into a good young man with extremely upright views. But who will tell her how the little puppy turned into a big wolf dog when he grew up, and he only wants to knock her down?
