Murderer. (Yandere! Yoriichi x Reader)

It was the year 1964, and coming from a poor family, it wasn't a suprise to you that you were engaged to a man you didn't know. You soon learned that the man you were engaged to was a rich man, and he was to be the heir of the KNYTech Industries. "Hello... My name is Y/n L/n..." you spoke out. He stared at you, his cold eyes making you nervous. "...My name is Yoriichi Tsukiguni." he replied, you glanced at his handsome face. You quickly looked away and blushed as he caught you staring. You were ready to accept all his imperfections but... Nothing could ever prepare you for his darkest secret.
