at least when it comes to Kazukage it makes sense that he'd simply run away instead of asking clarifying questions or wait for a complete answer.
but I do think that the extent to which the author's using "I disengage from conversation" as the default to keep the story suppressed risks becoming a crutch if things are simply left unspoken for too much longer. Even if it's only chapter 6, there's enough stuff in play that the Leads could actually talk, rectify the misunderstandings and miscommunication between them and become a unified pair, and still have plenty of external points of tension and drama to create an interesting narrative.
Having them fighting themselves, one another, and the world around them is a bit too much, I think. Kazukage is already beaten down as a person, clearly since childhood--as it stands, he arguably needs more than simply "Karen being present" to not run away completely, so hopefully the next chapter actually sees them talk and sort all of this out.
