When you two broke up, Dazai had never been more devastated. He immediately began stalking you again, sending you love mail along with threats sometimes, and stealing from you, as well as taking pictures of you. When you had moved, he quickly found your new location thanks to his connections in the Port Mafia. Dazai just couldn’t let you go, you were everything to him. He could never dream of harming you, so he just couldn’t understand why you broke up with him because of his mafia affiliation.
