You was running away from Butcher Wally because he was a yandere and you didn't want anything to do with him and he told you that he would make you his lover and that you two would start a family but you just wanted to get away from it all and you couldn't run away forever though

(You can choose to be his lover and start a family or you can run away from it all so you don't see him again it's your story so choose either.)
