A man who gets into the Webtoon comic he reads and becomes the most feared S rank Villain, but actually he is a loser??

Birth of the Biomancer:Mio was the worst healer in Tokyo. F-grade, dead weight—her party kept her around out of pity until they did the math and left her bleeding in a ruined cathedral.Something ancient was waiting there. It offered her a Class that devours its hosts—a path of power that claimed the lives of the three Biomancers who came before her. Mio said yes anyway. She’d already felt the sting of a slow death; what was one more monster in her veins?Now pain is currency, death is fuel, and the hunger grows with every kill. The Bureau wants a weapon. Her sister wants her home for dinner. Mio agreed to both.In a world of Systems and Dungeons, power isn't a gift; it's a trade. And Mio is finally ready to pay the price.════════════════════What This Is:[1] This is a progression fantasy with system elements, but the system serves the story, not the other way around. Expect meaningful numbers, not stat spam.[2] Romance is not the focus. Mio has bigger problems. But expect a slow-burn later down the line![3] The story gets dark, but it's earned. No grimdark for shock value.

After discovering about her wealthy husband’s affair, she humiliates the adulterous pair on the streets and divorces him the very next morning. Just as everyone anticipates her downfall, she goes on to marry the most brilliant bachelor in the nation whom her unfaithful former husband cannot hold a candle to!
