What do you mean? Like, are you getting to the sewers to start the investigation, or are you trying to fight a rat in the later story?
In previous versions of the game it was easy, as soon as you woke up, going to work for boss and then immediately back home did the trick, but now that they changed how energy works think it might be more difficult.
While annoying, you can just go back to and from between the neighborhood and home until it triggers, since don't think you have the wolf/boar during that chapter.
