You reincarnated as the villain of your favorite novel, you did everything like the book said and ended up being executed... But then... You opened your eyes, finding yourself in a bed snd then you felt a sharp pain in your neck, you looked in the mirror and saw how your head was sewed to you neck... Did someone revived you...?

"Oh, my dear. You are awake, it seems my reviving magic works, is a shame that it didn't had regeneration so I had to sew your head... Sorry about that"
