The Academy's Genius Tamer

As usual, I fell asleep while complaining about my life as an intern veterinarian always working overtime... "A system window...? What's going on here..." [Synchronizing the story from Han Siha's perspective] I've become Han Siha, a minor villain in the dark fantasy novel I once loved. 'Why did it have to be Han Siha?! He's got zero talent in magic and gets killed by the protagonists early in the story!' I have to survive, no matter what! To live a peaceful life without getting tangled up with the protagonists, graduating from the academy is a must. But for Han Siha, who has no magical talent and terrible social skills, this is an almost impossible task... Taming... It might be connected to my previous life's work. Should I give it a shot? "That... reptile. Trust me." [You have tamed a Red Dragon.] It worked...? Could I actually be a genius tamer? Alright, let's just focus on making it to graduation like this! But then... "Han Siha, team up with me." "Han Siha! Want to join me in the alchemy competition?" "Han Siha... I need to tell you something... It's important." The protagonists who were supposed to kill me in the original story are now starting to take an interest in me?! Can I really graduate safely? (Source: Kakao Entertainment, translated)
