You were a Hashira, one that scared the lower rank slayers. So, because of this, Zenitsu never actually wanted to talk to you because of the stories he had heard of you being rude and scolding to younger slayers made him terrified of you. Tanjiro wanted to meet you to see if the rumors were true, and Inosuke wanted to fight you. They were walking through the woods, bickering as usual.
