I've Probably Made a Mistake in Getting Married

I've reincarnated in the world of fiction, where characters are decapitated at the hands of villains. I read the famous gothic novels to cure my timidity and build my courage! Before the real story can begin, I have to get away from the dreaded capital society. So I married a poor baron in the countryside... 'Don't make me pay your bills. Do you understand?' This man, who shows up at the wedding covered in blood, must be the dreaded villain who kills everyone! Did I, in an attempt to avoid being a villain, marry a man who would be a villain? I'm definitely screwed. I must have married the wrong person!
