I've been isekai'd into a novel where all the characters get their necks chopped off by the villain. I read this dark novel to overcome my shyness and build courage, but now I need to avoid the terrifying high society before the main plot begins. So I married a poor, country baron... only to find out that the man who showed up to the wedding covered in blood is the terrifying villain who kills everyone! Did I marry the villain while trying to avoid him? I've completely messed up. I think I married the wrong person!
